Best .300 Blackout Suppressors: Top 4 Expert Picks

The .300 AAC Blackout has been a popular rifle cartridge since its introduction by Advanced Armament Company (AAC) in 2011. Initially developed for the U.S. Army, the civilian market quickly discovered that the .300 AAC Blackout was an effective sporting load, especially for wild boar hunting.

The popularity of this .30 caliber cartridge among coin hunters is astounding. Many night hunters use camouflage to approach their prey. Suppressors have become increasingly common in these groups to tame the wild muscle response of AR weapons. Suppressors are also popular with sport shooters and competitive shooters in target practice. Disconnected rifles are more comfortable for all participants to shoot with.

This article covers the major suppressors on the market for the .300 Blackout cartridge. In my reports, I will discuss construction, quality, design and performance. We hope this review will give you a better understanding of how to evaluate suppressors and what to look for in a suppressor for your weapon.

Legality issues

Before you consider buying a suppressor for your .300 Blackout rifle, determine if it is legal to have one where you live. The only way to be sure is to consult someone in your jurisdiction who is qualified to speak on this subject. In general, however, the laws on the possession of silencers are divided as follows.

Federal law

Possession of suppressors is legal under federal law, but is monitored and regulated by the Bureau of Alcohol, Tobacco and Firearms (BATF). You must contact the BATF to get a tax stamp for each suppressor you own.

National law

Forty-two states currently allow the removal of property. Eight states prohibit individual possession of silencers:

  • California
  • Delaware
  • Hawaii
  • Illinois
  • Massachusetts
  • Big Apple
  • New Jersey
  • Rhode Island

The District of Columbia has also banned the possession of suppressors.

Local Government Regulations

Some cities and counties have also enacted ordinances prohibiting or restricting the possession of suppressants in their jurisdictions. Your best bet is to contact your local police to find out if owning a silencer is legal in your town.

Best Blackout Suppressors .300 Buy

We didn’t include the suppressors in our list because, frankly, the high-level suppressors do pretty much the same thing. Let’s face it, a five decibel difference in noise reduction is not detectable without sophisticated testing equipment. Rather, it depends on the design and quality of the materials. Other factors, such as ease of maintenance and repair, are also important. It’s my pick for the best .300 blackout suppressors.

Testing Gemtech’s GMT-300BLK Suppressor

Sieg Sauer SRD762TI-10 Overview

Sig Sauer is known for producing the highest quality firearms available on the civilian market. Their weapons are legendary. Sig Line pistols are fired and carried by professionals and civilians around the world. The same attention to quality and reliability can be found in Sig Sauer’s range of silencers.

The Sig Sauer SRD762TI-10 is another cross-cartridge silencer. This Sig silencer works with .30 caliber ammo from 7.62NATO, 200 Win Mag and .300BLK. Expect a rich list of topics from Sig Sauer, and you will not be disappointed.

  • Construction – 5. Class Titanium
  • Assembly with straight wire
  • Ten baffles for maximum noise reduction
  • Rear mounted pliers for quick and easy assembly and disassembly.
  • Black Cerakote finish for enhanced durability
  • The caliber is 7.62 NATO

  • Overall length – 6.9 inches
  • Thread – 5/8 x 24 TPI
  • Weight – 13.5 ounces
  • Fully automatic evaluation
  • Acoustic insulation – 137cb

The Sig Sauer SRD762TI-10 is not the smallest or lightest damper on our list. The overall diameter of the tube is slightly larger than most other suppressors we profile. However, when it comes to durability, noise reduction and build quality, you won’t find many other suppressors that can compete with it.


  • Good noise reduction
  • Helps reduce perceived adversity
  • Well built and robust
  • Can be used with quick release systems


  • Not as quiet as the other oppressors.
  • A larger tube diameter can be a problem with some visor systems.

The Sig Sauer SRD762TI-10 may not be the best suppressor on the market, but it is certainly one of the best. If appearance is an issue, you can skip this Sig Sauer suppressor. However, if performance and maintenance are the most important factors, you should definitely consider the Sig Sauer SRD762Ti-10 silencer for your .300BLK rifle.

Radical firearms 7.62 Consideration of direct wire removal

If you’re on a budget, finding a decent muffler can be a challenge. Radical Firearms has risen to the challenge with its line of DC suppressors. Radical firearms are much cheaper than the other devices on my list, but they perform much better than their price.

Radical Firearms 7.62 Straight Thread Suppressor is the work of one man. I would call it utility design and manufacturing. These oppressors follow the concept of function before form. While this approach can reduce costs, it can result in a less visually appealing final product.

Radical Designs did not neglect to look at features and performance.

  • Calibration value – 7.62 NATO
  • Construction – Stainless Steel
  • Finishing – High temperature porcelain stoneware
  • Layout only for semi-trailers
  • Overall length – 9 inches
  • Weight – 20.4 ounces
  • Diameter of the tube – 1.5 ounces
  • Thread – 5/8 x 24 TPI

Yes, this silencer is simple and clear. But for about half the price of the other suppressors on my list, the Radical Firearms 7.62 Direct Thread Suppressor works similarly to all the others. In terms of what is considered a budget suppressor, radical gun suppressors are incredibly valuable.


  • Construction sold
  • Good noise reduction
  • Clean lines and no frills
  • Straight-thread nozzles for hard and rigid constructions
  • Grand Prix


  • The finish may not be as smooth as some other suppressors.
  • It may take some work on the weapon to get a perfect fit.

For the hunter who considers a rifle a tool, or the distance enthusiast who wants to shoot more comfortably, the Radical Firearms 7.62 Direct Thread Suppressor is the best choice. These silencers are functional, quiet and reliable. You don’t have to spend a fortune on a good muffler.

The weakest for Buck.

When choosing a suppressor, the aim should always be to minimise the effect on the terminal. The goal is to make it all quieter. In general: The quieter you want to be, the more money you have to spend. We hope this article has given you an insight into how to find the best suppressor for your .300 BLK rifle. There are hundreds of options on the market. Do your homework and then enjoy the peace and quiet.

The Top .300 Blackout Suppressor in the Market

Our Best Choice

Gemtech GMT .300 Blackout Suppressor

Gemtech GMT

Check on Impact Guns

  • Design makes it easy to clean.
  • Light and durable.
  • Very quiet.

Up to a 39dB reduction in sound, and a two-piece construction that makes routine maintenance easy. That—accompanied by its lightweight and smaller profile—makes the Gemtech your best bet.

The Top 8 Best .300 Blackout Suppressors

1. Gemtech GMT .300 Blackout Suppressor 

Gemtech GMT

Best Overall 300 Blackout Suppressor

What really sets the Gemtech GMT .300 Blackout Suppressor apart is its two-piece construction, which allows for easy comprehensive routine maintenance of the unit. 

Check on Impact Guns

That—in conjunction with being manufactured out of a titanium G-core material—leaves you with a suppressor that will outlast most of its competitors (particularly at its price point).

Rated at a 36-39dB reduction for either supersonic or subsonic ammunition, it's one of the finest sound suppression systems on this list. At only 14 ounces and 6.7 inches in length, it’s both one of the lighter silencers and one with the smallest profile.

It’s the only model on this list that isn’t rated for automatic fire, so if that is your primary use of the tool, then this silencer isn’t for you. Nothing wrong with that. Right tool for the job and so on. 

But this model is one of the absolute best at what it does.


  • Design makes it easy to clean.
  • Light and durable.
  • Very quiet.
  • Available in multiple calibers.


  • Not rated to handle automatic fire.

2. Silencerco Omega Suppressor

Silencerco Omega Suppressor

Best for 5.56 and 300 Blackout 

The Silencerco Omega Suppressor blows other suppressors away when it comes to cartridge options. 5.56 mm NATO, 300 AAC Blackout, 300 Winchester Magnum, and 7.62 mm NATO.

Check on EuroOptics

Manufactured out of stainless steel, titanium, and stellite, this model is as tough as it is versatile. Making it a favorite amongst firearm enthusiasts of every ilk. In that vein, the included quick-release mount allows for a fast and easy breakdown or swap.

The anchor break knocks recoil down considerably and makes this model the best flash 300 blackout suppressor on this list, too.

It comes in at only 14 oz. It’s also one of the shortest cans on this list, making it a more convenient home defense model. 

In the 300 Blackout, Silencerco’s claims that it reduces sound to 119dB holds up.

All in all, the Omega by Silencerco is the runner up on this shortlist of best suppressors.


  • Caliber options.
  • Quick-release system.
  • Short and light can.
  • Rated for automatic fire.


  • Slightly longer and wider than some of the other silencers on this list.
  • I’m going to have to be as quiet here as the can is.

3. Advanced Armament – Cyclone Suppressor .300 AAC

Advanced Armament

Best Budget 300 Blackout Suppressor

The Advanced Armament – Cyclone Suppressor .300 AAC is a CNC machined aluminum suppressor. It comes in with the tightest metaphorical grouping of function, cost, quality, and longevity. 

Check on Brownells

One should work with ear protection as much as possible (or so I used to hear) but this suppressor is rated to reduce decibel levels by 30-33dB. Paired with the right ammunition, it can really help prevent damage to one's auditory tissue, even without ear protection.

The machined fit threading at ⅝-24 is consistent and tight. The device functions well as a recoil compensator and of course—dampens flash. 

At only 22.4 oz of aluminum, it’s a light easy addition to any system, and it costs less than half of similar models.

Simple, reliable, versatile, and affordable. The Cyclone suppressor might not be as easy to maneuver as other models on this list, but it is unquestionably the easiest on ones bottom line.


  • Unparalleled affordability.
  • Durable machining.
  • Reliable functionality.
  • High-quality sound reduction.
  • Rated to handle automatic fire.


  • This is the heaviest silencer on this list. It’s still light, but not the lightest.
  • At 9.5” this is the longest can on this list. Not a deal-breaker, but overall length impacts handling for any close quarter purposes.

4. SIG Sauer SRD762-QD

SIG Sauer SRD762-QD

Versatile 300 Blackout Suppressor

Relative newcomer to the suppressor game, SIG Sauer came in guns blazing onto the scene with their specific brand of manufacturing competence.

Check on Brownells

The SIG Sauer SRD762-QD is built out of the superalloy, Inconel. This leaves the unit with significant resistance to metal fatigue. Ideal for carbines, which are notorious for beating up cans like an old boxing champ coming out of retirement.

Along those lines, in coming in at 17 ounces and only 7 inches long, this model seems perfect for home defense carbines.

On top of all that, Inconel bleeds heat faster than most materials. Because an accidental brand is only funny if it’s between bros (likely under the Kyle banner).

Available from .204 Ruger, up to .308 win mag, so this model’s versatility isn’t in question.

SIG might be new to the silencer game, but they learned from the mistakes of their predecessors and stand on the shoulders of giants. The SRD762-QD is testament to such. 


  • So many caliber options.
  • Quick-release system.
  • Short and light can.
  • Rated for automatic fire.


  • Slightly heavier than other models on this list.

5. Silencerco Saker 7.62mm

Silencerco Saker 7.62mm

Value 300 Blackout Suppressor

The Silencerco Saker 7.62mm might offer the best sound reduction per dollar on the market. The price is great, and Silencerco makes excellent suppressors.

Check on Brownells

The flagship feature of this suppressor is the retention system. Silencerco’s Active Spring Retention (ASR) System makes this suppressor compatible with a variety of flash hiders, muzzle brakes, and direct-thread mounts. So, this is a great suppressor for anyone who wants to use a single suppressor for multiple rifles.

And, with subsonic ammunition, this suppressor reduces the sound signature to 132 decibels, which is hearing safe.

Additionally, this suppressor is constructed from stellite cobalt-chromium alloy and stainless steel, which provides optimum corrosion resistance. And, the angled Hoplon baffle design redirects gas to the outside of the baffles to reduce carbon foulingBoth these features extend this suppressor’s lifespan and make for less frequent cleanings.

Lastly, this Silencerco model is rated for full-auto fire. But, even if you don’t have a full-auto rifle, the added durability makes it even more resilient in semi-auto operation.

Unfortunately, all the functionality requires some hardware. So, this suppressor measures 10 inches long, which can be a bit much on longer barrels. This suppressor is best for short-barreled rifles.

But, the longevity and performance are an especially great value for the money.


  • Compatible with a variety of flash hiders, muzzle brakes, and direct-thread mounts.
  • Reduces sound signature to hearing safe levels.
  • Construction materials and baffle design extend service life and cleaning intervals.
  • Full-auto rated.


  • Adds quite a bit of length to your barrel.

6. Gemtech HVT-QD Suppressor

Gemtech HVT-QD Suppressor

Tactical 300 Blackout Suppressor

The Gemtech HVT-QD Suppressor is quiet, yes. But, it also has a few extra features that make it ideal for tactical operations.

Check on Brownells

First, the noise reduction is 30db, which brings the sound level to hearing safe. And, with proper .300 BLK ammunition, the sound of the bullet in flight is enough to mask the sound signature. In short, this is a really quiet suppressor.

On the outside, this can is cerakoted. It’s a thick, durable finish that reduces visible light glare and the visible IR signatureYou could easily add this suppressor to your kit without painting it.

This suppressor is compatible with Gemtech’s quick detach system, which might be the simplest quick detach system on the market. The quick detach mount threads onto the barrel. Then, the suppressor attaches and detaches quickly with a fast, one-handed movement. Unfortunately, the QD adaptor is sold separately.

Also, this is not a compact suppressor. The overall length is 9.2 inches. So, it’s best for short-barreled rifles. Otherwise, it can be a bit unwieldy.

All in all, this might not be the smallest muzzle device, but the performance more than makes up for it. Equipping this suppressor will surely give your blackout rifle an outstanding shooting accuracy.

Aside from suppressors, hearing protection must also be equipped to reduce the noise and avoid unwanted injuries.


  • Excellent sound signature reduction.
  • Thick, durable cerakote finish improves corrosion and wear resistance.
  • Exterior finish reduces visible IR signature.
  • Quick detach system is incredibly simple and easy to use.


  • Quick detach mount is not included.
  • Not compact at all.

7. Dead Air Armament Sandman-S Suppressor

Dead Air Armament Sandman-S

Compact 300 Blackout Suppressor

The Dead Air Armament Sandman-S Suppressor is one of the shortest 300 Blackout suppressors on the market. And, it sacrifices very little performance to get a more compact form factor.

Check on EuroOptic

Right up front, this suppressor is just 6.8 inches long, and weighs 18.5 ounces. So, it’s short and light. This is ideal for full-length rifles and those who need to run a lot of accessories on their forend.

And, even though it’s small, it still reduces the sound signature to hearing safe levels (though just barely), if you use subsonic ammunition. However, this suppressor is not hearing safe with 7.62 or .308 rounds.

The baffles are made of stellite and welded into a solid core for maximum durability. And, the end cap is replaceable, in case you drop your suppressor and ding the muzzle or get a baffle strike.

Lastly, the Dead Air quick detach system is quick and easy to use. And, the secure locking mechanism reduces point-of-impact shift and maintains your rifles precision, with or without the suppressor.

So, if you have a full-length rifle that you want to suppress, or if you just want to keep your platform as compact as possible, this is the suppressor to get. Very few suppressors offer such a good combination of size and performance.


  • Very compact design.
  • Reduces sound signature to hearing safe levels.
  • Welded, stellite baffles form a solid core for outstanding durability.
  • Quick detach system is quick and easy, and maintains your rifle’s precision.


  • Sound reduction is just barely hearing safe, and only with 300 BLK ammunition.

8. Surefire SOCOM 7.62-RC2 Suppressor

Surefire SOCOM 7.62-RC2

Quick Detach 300 Blackout Suppressor

The Surefire SOCOM 7.62-RC2 Suppressor is one of the most popular suppressors on the market, despite the relatively high price. That’s because the performance is excellent.

First, this suppressor reduces the sound signature to hearing safe levels, even with higher pressure rounds like 7.62×51 and .308. With subsonic ammunition, 300 BLK is insanely quiet from this suppressor.

Second, this suppressor is compatible with most Surefire SOCOM suppressor adaptors. So, you can mount this suppressor over a flash hider or muzzle brake, if you want. However, you must use a Surefire muzzle device, if you want to attach this suppressor over a muzzle device.

Then, this suppressor is just 8.4 inches long. It’s not the shortest suppressor available. But, it’s impressively short considering the noise reduction. And, it’s compact enough to use with full-length rifles without too much difficulty.

The design and quick detach system also minimize the shift in point-of-impact. This is ideal for rifles with longer barrels, since it helps retain the organic precision, even during suppressed fire.

Unfortunately, the price on this Surefire suppressor is a tad restrictive. But, the performance might be well worth it, especially if you’d like to do long-range shooting with a suppressed rifle. Another piece of advice on enhancing your rifle is to invest on quality buffer spring to improve functionality as well as reduce noise.


  • Excellent sound reduction with all compatible calibers.
  • Compatible with Surefire SOCOM muzzle devices.
  • Fairly compact.
  • Minimal shift in point-of-impact.


  • Expensive.
  • Quick detach system only works with Surefire muzzle devices.

In with a roar, out with a whisper.

The Gemtech GMT .300 Blackout suppressor checks off all the boxes any shooter could have.

300 Blackout: Shooting with Subsonic Ammo

One of the hottest new rounds to emerge in the past few years is 300 Blackout; this is a true dual-purpose intermediate sized cartridge that can be fired in both subsonic and supersonic loads. It was designed to be used in AR-pattern rifles with only a barrel change to convert a traditional AR-15 rifle from 5.56 NATO. It has since become one of the most popular rounds to use with a suppressor.

This relatively new cartridge has been around a bit longer than some might think and has its share of fans and detractors, but 300 Blackout has more than proven itself as a hunting, defensive and target round in that time. It may not be the be-all and end-all cartridge, but for most shooters and hunters, 300 Blackout is worth taking a second look at.

What is 300 Blackout Ammo?

The 300 Blackout round has its roots in the 300 Whisper cartridge designed by JD Jones of SSK Industries in the early 1990s. Jones formed the brass from 221 Fireball cases expanded to take a .30 caliber bullet. By varying the load, lighter bullets could be fired at supersonic levels with the power of the Soviet 7.62 x 39 or used with heavier bullets at a subsonic level for use with a sound suppressor.

Unfortunately, the round was trademarked by SSK and other manufacturers were unable to manufacture barrels or even brass and dies for the round. The 1994 Federal Crime Bill and Assault Weapon Ban did not help the subsonic cause, either, as threaded barrels on semi automatic rifles made them subject to the ban. National Firearm Act laws governing the sales of silencers were also misunderstood at the time and silencer ownership was a mere sliver of what it is today.

It seemed as if the round was doomed to die in the “also-ran” wildcat category until the Federal Assault Weapon Ban was allowed to sunset in 2004 and a company called Advanced Armament Corporation (AAC) began to show interest in the 300 Whisper.

AAC was eventually bought out by Remington Defense and the two companies worked on the design as a potent new caliber that could address perceived shortcomings with the 5.56 NATO round.

Remington and AAC changed the design slightly by using trimmed and expanded 5.56 NATO brass as opposed to 221 Fireball or 222 Remington as the parent case. They normalized different load data and submitted the new cartridge to SAAMI (Small Arms Ammunition Manufacturers Institute) and CIP (Permanent International Commission for the Proof of Small Arms) for standardization and christened the new round 300 AAC Blackout by CIP and 300 BLK by SAAMI.

The improved design means that it will work with a standard AR15 or M16 bolt and magazines with the only real part change being the barrel. Another positive note is that 300 Blackout and the original 300 Whisper cartridge are completely interchangeable from barrels to reloading dies as well as reloading components and specifications.

As a result of its popularity we have even seen the retail price of 300 Blackout ammunition decrease over time. This is always a good sign with regard to the longevity of an ammunition cartridge in the market.

Performance and Ballistics

In its standard form as a subsonic round, 300 Blackout most closely resembles the 7.62 x 39mm round first used in the SKS and AK-47 rifles of the former Soviet Union. In its subsonic loading it has been compared with both subsonic 9mm and 45 ACP.

One of the main reasons that the US Military was looking for a replacement round for 5.56 NATO was the loss of energy and velocity by the 5.56 NATO round as it was fired through barrels that were increasingly getting shorter.

The 5.56 round was developed for use in 20” barreled rifles. Severe deficiencies were found when trying to make the military service rifle shorter. Additionally, the use of a suppressor dictated going to a shorter barrel as soldiers were finding full sized rifles becoming unwieldy with a 5” to 8” sound suppressor mounted on the muzzle. Another consideration here was the effect of the initial blast of unburnt powder and flash increasing wear on the initial baffle of a 5.56 suppressor.

300 Blackout was optimized to be fired through shorter barrels and even in supersonic loadings it did not have that initial blast problem. The round exceeded most military expectations for the caliber in both subsonic and supersonic renderings.

On the civilian side, 300 Blackout has proven to be a performer in the field for hunting and on the competitive shooting circuit.


Popular Comparisons

Every new cartridge is often compared to an older one and 300 Blackout is no exception. These comparisons are both a good thing and a bad thing for a few reasons.

On the good side, hunters and shooters generally want an idea of how a new round will perform. Comparing 300 BLK to an existing round with regards to bullet weight, caliber, velocity and energy sets the stage.

So the 300 Blackout supersonic loads are compared to rounds such as 30-30 Winchester and 7.62 X 39mm. This gives a shooter an idea of what to expect recoil wise and the intended use of the round.

Another consideration for rifle shooters is often the size of the rifle’s action. While this was addressed initially by use of 300 Blackout in the AR-15 or M16 platform with regard to bolt face, magazine configuration, etc, it is also an important consideration for use in a bolt action rifle.

For the bolt action rifle shooter, action length is often an important consideration, as this can affect the weight of the rifle and its overall configuration for handling recoil. Typical bolt action lengths are referred to as short, long and Magnum. The long action is used for rifles chambered in calibers such as 30-06 Springfield. Magnum actions are intended for powerful belted magnum cartridges such as 300 Winchester Magnum, 459 Winchester Magnum or 375 Holland & Holland. The short action is intended for everything from 17 Remington up to 308 Winchester and this is the size needed for a bolt action rifle chambered in 300 Blackout.

The subsonic 300 Blackout loads are often compared to 45 ACP, 10 mm or 9mm subsonic rounds. This showcases the dual purpose of the round. The advantage of 300 Blackout is if the shooter wants an AR-pattern rifle or pistol that is easily suppressed, they can use a common magazine and typically only need to swap an upper receiver. Pistol caliber conversions for the AR platform often need different magazines, buffer assembles and other changes to make them effective and reliable.

Where it becomes a bad thing is that these comparisons rarely give the complete picture to the shooter or hunter and can actually be a disservice to 300 Blackout and to the round to which it is being compared.

300 Blackout vs. 556

The most obvious comparison for 300 Blackout will be made with 5.56 NATO. After all, this is the round it was intended to dethrone.

As we stated earlier, this is a disservice to both cartridges. The 5.56 NATO round has a longer range, higher velocity and some would say more inherent accuracy. In its supersonic loading, 300 Blackout shares similar characteristics with the 7.62 X 39mm round which has often been set up as the rival of 5.56 NATO for the past 60 years.

Terminal ballistics for both rounds as a military cartridge will be compared ad nauseum. A lighter bullet in the form of 5.56, by as much as two to 3 times the weight, travelling at 75% to 100% of the velocity has its advantages over the heavier and slower 300 Blackout. Yet some troops would say that a heavier and slower bullet may not have the penetration ability of the 5.56 but addresses the overpenetration issues noted by US Army Rangers and Infantry in operations in Somalia where the 5.56 required multiple hits on target to dispatch an enemy soldier, whereas the 7.62 x 39mm seemed more effective at stopping an enemy combatant with a single round.

One of the dangers of keeping both rounds in the same collection is that 300 Blackout will actually chamber in a 5.56 rifle. It cannot be safely fired from that platform without causing a catastrophic failure to the firearm and injury or possibly death to the shooter and those in close proximity.

For this reason, we recommend that if you shoot both calibers to incorporate some variables with regard to your shooting components and accessories. For example, use one type or color of a magazine for one round and a different one for the other. This can be taken a step further by loading 300 Blackout subsonic rounds in a different magazine size from the 300 Blackout supersonic rounds so that a supersonic round does not accidentally go through a pistol caliber or 300 BLK subsonic rated suppressor accidentally.

The key advantage here is that AR magazines are inexpensive when compared to just about every other platform out there. This is another inherent advantage of 300 Blackout.

It is not a bad idea to ensure that the upper receivers can be easily distinguished, whether by different optics, rails or colors.

300 Blackout vs. 350 Legend

When 350 Legend debuted, Winchester claimed it was the fastest straight wall cartridge ever released. Like 300 Blackout ammunition, it had the ability to be loaded to subsonic or supersonic levels and it would fit in a standard AR15 action and magazine. Some hunters speculated that it would sound the death knell for 300 Blackout due to the fact that hunters in some north eastern and midwestern states were limited to hunting deer with a straight wall cartridge.

As fine a cartridge as it is, 300 Blackout had the advantage in that it had more than a 10-year head start on 350 Legend. There are simply more barrels, magazines, rifles, pistols and other accessories dedicated to 300 Blackout as opposed to 350 Legend.

350 Legend certainly has the upper hand as a hunting caliber in states where bottleneck cartridges are prohibited for big game hunting and performs well on animals like deer and black bear, but it will not overtake 300 Blackout on the whole anytime soon.

The other disadvantage is the limited amount of .35 caliber suppressors made for the supersonic load in 350 Legend. Subsonic 350 Legend can be safely fired through most 9mm suppressors in the same manner as 300 Blackout subsonic.

300 Blackout vs. 223

While 5.56 NATO and 223 Remington are used interchangeably, they are not the same round. The 5.56 NATO is loaded to a higher pressure level than 223 Remington. Furthermore, 223 Remington is considered a commercial civilian use round, making it more suitable for hunting applications, not unlike the 300 Blackout supersonic load.

In this regard we often see more soft point, hollow point and general use hunting rounds in 223 Remington as opposed to 5.56 NATO. However, 223 Remington is considered more of a small game or varmint round, as opposed to a heavier round like the 300 Blackout.

Again, it goes back to the purpose of the round and shows how a long range varmint round, as was the original intent of 223 Remington, cannot be justly compared to a slower, heavier bullet like the supersonic 300 Blackout. 223 Remington is ideal for coyotes and prairie dogs at long range whereas 300 Blackout is more suitable for deer or black bear at shorter ranges.

Shooting 300 Blackout Ammo with a Suppressor

As we mentioned numerous times by now, 300 Blackout has a subsonic range of ammunition choices and makes for an excellent suppressor host. The advantages are two-fold in that if one sticks to strictly subsonic loads they can shoot through a suppressor rated for 45 ACP or 9mm. Should the shooter wish to shoot the supersonic round suppressed, a silencer rated for 308 Winchester will easily handle both supersonic and subsonic loads.

300 Blackout subsonic is one of the quietest rounds to suppress, particularly when fired through a closed breech firearm like a bolt action or single shot rifle. There is no noise from the action or any created via the ejection process as noticed in a semi automatic firearm.

Additionally, we find 300 Blackout in supersonic form to have a very mild and pleasant tone when fired through most suppressors rated for 308 Winchester. It may not be as quiet as a 300 BLK subsonic, but sometimes absolute silence is not the goal.

Is 300 BLK good for Hunting?

The 300 BLK round is an excellent cartridge for hunting. Ballistically it performs similar to 7.62 x 39 or maybe the great American hunting round known as 30-30 Winchester or 30 WCF (Winchester Centerfire).

300 BLK has one distinct advantage over 30-30 Winchester in that 300 Blackout can use more effective Spitzer type bullets, where this is a rarity in most rifles chambered in 30-30 Winchester due to the use of a tubular magazine found on most lever action rifles chambered in 30-30 Winchester..

Likewise, 300 Blackout is a superior hunting round to 7.62 X39 because most 7.62 X 39mm ammunition is Berdan primed and steel cased and therefore non reloadable. Plus, 300 BLK has many more options with regard to bullet choices more suitable for hunting.

300 Blackout for Deer Hunting

Although it may not look like it at first glance, 300 BLK makes an excellent choice in a cartridge for deer hunting. There is a wide variety of factory ammunition and reloading components to make this an excellent short range deer slayer.

They key is to run the 300 BLK with supersonic loads and an appropriate projectile. This will allow for proper penetration and expansion and a marked level of improved performance when it comes to terminal ballistics. Simply put, the 220-grain subsonic loads will not give you that performance on a deer.

Another consideration is range – we find the 300 Blackout perfectly acceptable for taking deer within 150 yards. Performance is quite similar to the 30-30 Winchester, only we feel it is a more accurate round with much better projectile options for terminal ballistics on big game.

Closing Thoughts

300 Blackout is at the very least a very interesting and diverse cartridge for the shooter, hunter and especially a home reloader. Its dual purpose gives it a very distinct role in both personal defense and shooting sports. 300 Blackout seems to have become a mainstream round in the past decade alone, despite its origins in the 1990s in the form of the 300 Whisper wildcat type of round. As a subsonic suppressor host or as an intermediate hunting caliber, we expect to see 300 Blackout stay around for at least another half a century.

Both are rated for 300 WM - I can shot mine a few times without ear pro. I would like the 7" better as mostly it lives on my BLK and second most is shooting 308 with it.

Don't know if $$$ is going to be a factor yet. Depends on if i can sell some other stuff in the next few weeks. This will be on a 16" blk upper. Currently, my only threaded barrel of the 2 AR platforms i have. The 5.56 upper is a Heavy bull stainless 20" barrel that is not threaded...yet. I primarily bench shoot at the gun club so for now the weight is not an issue.

5 Best .300 AAC Blackout Suppressors & Silencers

Are you searching for the right suppressor for the .300 Blackout rifle?

You have come to the right spot, if you are. A.300 Blackout weapon can be very noisy.

But, using a high quality suppressor will reduce the volume of a shot significantly.

We’ve taken the liberty of selecting five of the newest & strongest .300 Blackout suppressors on the market.

You should also think about the lawfulness of the suppressors (and where they may or may not be legal) when we proceed through our review.

We’ll also give you a short tutorial about how to pick the right blackout suppressor.300.  

If you are a daily carry proponent you should thin about getting a Concealed Carry Insurance. Also check out our Best .300 Blackmore Rifles & the Best 9mm Revolvers.

Suppressors – Are they legal?

The quick reply: it varies form jursidiction to jurisdiction.

The long response is it’d depend in the state you ‘re staying in. 

Silencers are officially legal in 42 states.

Eight states are prohibiting the use of suppressors:

California, Delaware, Hawaii, Illinois, Massachusetts, New Jersey, New York and Rhode Island.

Also if the state requires suppressors to be used, double verifying will be wise for you.

Many states may disallow the usage of suppressors even though they are not prohibited by state statute.

For clarification, you may bookmark this article & check back to make sure that your state is one of the 42 states where it is legal to possess and use a suppressor.

 What to look for when picking a .300 Blackout Suppressor

It is beneficial to understand which .300 Blackout suppressor would better be focused on your specific wants and needs.

Simultaneously, you may need to weigh a few considerations which will play a role in your final decision.

If it’s your first time buying a blackout suppressor.300, you may want to pay careful attention to what you might be searching for.

Several elements and functionality that you will be searching for are as follows:


Performance is perhaps the most critical factor to remember while looking for a suppressor.

The quality rating would depend upon the materials from which the suppressor is made.

Manufacturers would most of the time utilize products such as titanium or steel. all of the suppressors here are known to handle some heavy beatings, and should still be able to tolerate some degradation or corrosion of some sort.


Obviously it needs to be mounted on your gun’s muzzle in order for the suppressor to function.

Most of the suppressors listed here are likely to be quick to mount suppressors that don’t need any hardware or skilled gunsmith ‘s expertise.

Most are welded in order to ensure rapid attachment and detachment.

Reduce Noise output

The lower the volume of sound of the shot, the stronger.

That is one thing you should consider when looking for a silencer. Look for a silencer which holds your gun’s noise below 140 decibels.

You will shoot your .300 Blackout weapon at those heights without any ear safety support.

When the noise rates are a bit too noisy though, you should also use ear protection.

This may actually be recommended if you plan to use your .300 Blackout in extended shooting sessions.

People asking also 

To make it easier to search for your next.300 Blackout suppressor, it’s important to consult the frequently asked questions.

This will explain any potential questions that you may have while finding a suppressor of your choosing. Below are few questions:

Wearing out Arms Suppressors?

The quick reply: depends.

The long answer: How old the suppressor is is the significant factor.

Many of the new suppressors these days would not be able to fit as quickly as the old school suppressor. Around the same time, it won’t be prone to rapid wear if the suppressor is solid and stable.

Are silencers compatible with every Rifle?

Ususally yes. The silencer must however be welded a certain way to fit the gun for which it was designed.

So certain silencers will in fact be equipped for other styles of firearms.

Similarly, the same can be done for certain rifle types too.

Are silencers the same thing as suppressors?

Yeah. The only distinction in this is the word.

More so, silencer is the legal way to say suppressor.

The above is therefore something of a scientific word. You should name it whatever you want, any way.

Can you build a suppressor legally?

Sure, you can create a suppressor, lawfully.

Only make sure you obey the rules and instructions as though you were producing a legitimate, licensed, NFA-approved weapon.

Know, it may rely on certain laws and regulations in your area or state as well.

Once again, step on the cautionary side and test the rules of your state and ensure sure you’re safe and clear of any legal problem that may occur.

Silencers: What you need to know about the technology

A single shot can cause lasting damage to the hearing of hunter and dog.

Silencers provide a remedy. We explain technical possibilities and limits.

The desire for the highest possible damping performance is understandable.

Even a comparatively low damping value of 20 decibels is equivalent to a reduction in sound pressure by a whopping 90 percent!

Even in this class of mostly very compact and light silencers, you do your and your hunting dog’s ears a lot of good.

With many hunters, however, the pain threshold is only undercut with a noise reduction of 25 to 30 decibels, so that one should then resort to more powerful models.

Silencers offer the hot and highly charged gases flowing out of the muzzle a space in which the extremely high pressure can be reduced.

When the gases then escape from the silencer into the environment, the much lower pressure produces an audibly quieter bang.

The more volume the damper provides for this, the greater the relaxation effect.

Very large dampers therefore generally reduce the noise of the shot better.

However, at some point in time, the practicability of this is limited by diameter, length and weight.

Complementary effects

In the silencer itself there are orifices that divide the inner life into different chambers.

When the bullet passes through, the openings in the baffles are temporarily displaced so that the gases behind them can only spread from chamber to chamber step by step.

Depending on their design, the orifices also cause turbulence in the gas flow: this helps the gas to flow out over a longer period of time.

This also helps to reduce pressure peaks.

The cooling of the vapour gases through heat absorption of the silencer also has a considerable effect, which additionally leads to a pressure reduction.

Silencers are usually made of the following materials:

Steel silencers have a very good heat absorption.

They are generally inexpensive and extremely robust.

On the other hand, they can rust if not cared for properly and are quite heavy compared to other materials.
Most hunting silencers are therefore made of aluminium.

Although they are usually a little less durable, they have less influence on the weapon balance and are corrosion resistant.

If you want to dig a little deeper into your pocket, you can go for titanium, which is more wear-resistant than aluminium.

Basically, the service life of silencers made of all materials available on the market is in the four-digit range for shot numbers.

They will therefore last at least “half a hunter’s life” without difficulty – as long as they are not overheated in longer series.

If you want to practice hard in the shooting range, it is best to use silencers made of steel.

If you can’t get away from the comfortable aluminium model, you should be disciplined:

As long as you do not exaggerate and – regularly – take breaks to cool down the equipment, even light models made of titanium or thick-walled aluminium shocks will survive high numbers of shots without damage.

The extremely light carbon silencers, on the other hand, are the worst choice for longer training in shooting movies.

Due to the material, they cope worst with the heat during longer series and run the risk of being damaged.

Not quite as long

Classic silencers have a thread at the rear end for fixing to the barrel.

They build in almost full length to the front and increase the overall length of the weapon accordingly. In contrast to this, the so-called telescopic or overbarrel silencers put their rear end over the barrel; the thread lies approximately in the middle of the silencer.

Both constructions have their advantages and disadvantages:

With the telescopic silencer the weight is a bit closer to the shooter, so that the balance of the weapon is usually a bit better.

At the rear end they have a plastic guide ring which is turned to the barrel diameter and serves as an additional contact point.

For an overbarrel silencer an open sight must be omitted. It is also no longer possible to mount the front sling swivel close to the muzzle.

With the classic standard rear shock, however, the front sight can remain in place.

If you choose models with a diameter of 40 or 45 millimetres, the sight line remains free in most cases and the open sight can be used despite the shock.

If possible everything from one source

A muzzle thread is a prerequisite for the attachment of a silencer to the weapon.

It is therefore recommended to always order a muzzle thread when ordering a new weapon.

If you have to have it retrofitted, difficulties may arise:

As a rule, the barrel bore is never completely aligned with the outer contour of the barrel.

If the gunsmith then simply clamps the barrel in the lathe along the outer contour, an alignment error can occur when the thread is attached.

If the muffler’s core is not exactly in the direction of the barrel’s core axis, the bullet’s aperture contacts may occur.

Serious damage to the silencer is very rare, but the firing performance of the weapon deteriorates significantly.

It is therefore absolutely necessary to place your gun in expert hands and ideally buy the silencer where the thread is also attached:

If the gun does not fire, the complaint is limited to one contact person and mutual blame is avoided.

Thread depending on barrel diameter

Silencers can be supplied by the manufacturers in all common threads.

When selecting the thread, the expert will orientate himself on the outer diameter of the barrel near the muzzle.

As a rule, a fine thread two millimetres smaller than the barrel diameter is best suited.

A 17 millimeter thick barrel should therefore be fitted with an M15 x 1, while an M17 x 1 fits a 19 millimeter barrel. If a thread with a difference of less than two millimetres from the barrel diameter is chosen, a sufficiently large shoulder is missing.

However, this is important for the correct alignment of the damper.

If you use considerably smaller threads, the reduced wall thickness, especially on hammered barrels, risks a muzzle expansion that is detrimental to precision.

In any case you have to make sure that you get a nut that protects the sensitive thread from damage when no damper is mounted.

Silencer Care for the Best .300 AAC Blackout Suppressor

Some silencers are modular, so that length, weight and performance can be changed almost at will by adding or removing orifice elements.

They also allow complete disassembly for cleaning.

Other silencer models can be opened for cleaning, but their composition cannot be changed.

Still other models are completely encapsulated: They can only be cleaned in an oil or ultrasonic bath.

Especially with steel silencers this makes sense because of the danger of rust.

This is because the deposits inside are hygroscopic, which means they bind moisture.

If you think this is too much effort, you should apply a short spray of oil to the interior after use and make sure it dries thoroughly.

From time to time, residues can be shaken out.

Under no circumstances should the weapon be stored permanently with the silencer mounted, otherwise corrosion at the muzzle will quickly occur.

One of the Best .300 AAC Blackout Suppressors for several weapons

Basically the hunter can use one silencer on several weapons.

It is only important that the size of the aperture openings also matches the caliber.

For example, the use of a .222 silencer on a 9.3 mm rifle is automatically forbidden: The 9.3mm bullet simply won’t fit through the silencer.

In the reverse example, the use of a 9.3 mm silencer on a .222 rifle is possible without difficulty, even if the silencing performance is somewhat reduced.

Some manufacturers offer products with exchangeable front parts or covers, so that the silencer can be converted for use with other calibers.

If you have several weapons in the same caliber, but with different muzzle thread types in the cabinet, it is also possible to use one silencer for all weapons:

Many products have interchangeable threads, so that you can use the one that fits your weapon.

Another variant offers the mounting of silencers on muzzle brakes.

Here, several weapons with different threads are equipped with a suitable muzzle brake or muzzle flash suppressor.

These then all offer the same interface for the silencer.

In some cases, manufacturers offer quick-coupling systems that eliminate the tiresome process of screwing and unscrewing.

What silencer caliber?

For use with silencers, short-barreled weapons are particularly suitable, so that the rifle still remains manoeuvrable despite the extension.

The disadvantages of a short barrel, i.e. stronger recoil and more muzzle flash, are more than compensated by the silencer.

Rifles with a barrel length of 45 to 50 centimetres are particularly well suited in combination with a centre cartridge with a comparatively small case volume, e.g. .308 Win. or 8 x 57 I(R)S.

Magnum calibers require special

Magnum cartridges can also be easily tamed with a silencer.

However, a radical barrel shortening makes less sense here, as the performance advantage of the cartridges is lost and the load on the silencer increases considerably.

In any case, Magnum silencers should then be used, which are adapted to the larger swath gas volumes.

One more positive side effect of using a silencer should be mentioned at the end: it usually increases the precision of the liner noticeably.

What types of silencers are there?

There are currently three types of silencers on the market. Those who are familiar with weapon technology will quickly recognize the screw-on-suppressor.

The silencer with thread can be quickly screwed onto a barrel with thread. Every gunsmith knows them and has different versions in stock. The only conditions that have to be fulfilled are a weapon whose barrel has a thread, the appropriate caliber diameter and the engraved serial number, which is registered in the WBK. This type has been produced in large quantities since about 1980.

The silencer with quick release uses an adapter or a special muzzle brake on the barrel. They are available with and without a lock.

The integral silencer is relatively new. I saw the first integral damped weapon in late 2015. The silencing technology is integrated directly into the barrel. The barrel and silencer are one piece. If you choose this type of weapon, you will either have to buy an integral silencer or have your existing weapon equipped with an integral silencer barrel. The idea of an integral silenced rifle barrel is finding more and more interest, especially in the USA.

Both the Blaser R8 Silence and the Steyr Breeze are not purely integral damped weapons.

Both manufacturers take a middle course and offer extremely short-barreled weapons with an over-barrel silencer over the entire barrel.

The actual barrel of the Blaser R8 Silence is 42cm and that of the Steyr Breeze even only 40.7 cm (with caliber .308 Winchester).

With the silencer screwed on, the guns are then (as usual) 115 or 117 cm long.

Advantages of the Best .300 AAC Blackout Suppressor

The “standard silencer” with thread is available everywhere, widely used and easy to clean.

Also for screw-on silencers, there are now multi-caliber silencers available, such as the Nielsen Sonic Ghost 50, which can be shot on several guns with different calibers.

The quick release has the advantage that the silencer can easily be changed from one gun to another (if both guns have an adapter mounted).

You often see shooters changing a .308 Win silencer with quick release to a .223 Rem.

The second advantage is the locking mechanism which prevents the silencer from coming loose when the gun gets warm (e.g. when training in the shooting cinema).

The integral silencer has the advantage that the heat is dissipated evenly and well and the silencer does not interfere with magnifications of < 4x even with small riflescopes.

In addition, it does not bring any possibly disturbing extra weight to the muzzle of the weapon and thus is less disturbing.

In general, silencers improve the accuracy of the weapon and the shooter (technically and psychologically).

Technically speaking, there is less turbulence at the muzzle, which affects the trajectory of the bullet, and psychologically speaking, there is considerably less recoil and less interference from the gunshot.

Therefore one “mucks” less.

Disadvantages of the Best .300 AAC Blackout Suppressors

In general, all types of silencers have the disadvantage that the weapon becomes heavier.

Especially the screw-on and quick-release silencers mounted on the muzzle make the gun a bit top-heavy.

To counteract this, there is a version as an “over-barrel” silencer, whose thread (or quick-release fastener) is not in the end but inside the silencer.

With such a silencer the front sight must be removed in any case.

The integral silencer or integral silenced gun has the additional disadvantage that I am not allowed to go hunting with the gun in (federal) countries where hunting with silencers is prohibited.

A further disadvantage is, in my opinion, the fact that one is technically committed.

If in a few years better or different silencing technology is developed, you cannot change.

The weapon becomes more dirty when shooting with silencer.

This is due to the fact that pressure builds up in the silencer, which is discharged forward after the bullet has passed through it.

Due to this ram pressure, a little more gun smoke remains in the barrel.

Does it only “piff” when I shoot with silencer?

It is not quite like in the movie. This is because the shot is actually composed of two bangs.

One is the muzzle blast, which is caused by the gases (which drive the bullet) at the muzzle suddenly expanding and creating an explosive bang.

You can influence this noise with the silencer.

The second bang is caused by the bullet flying at supersonic speed.

Like the bang of a fighter jet breaking the sound barrier in flight.

The silencer cannot influence this supersonic bang.

It is, by the way, the louder component of the gunshot.

The only way to make it as quiet as in the movies is with a silencer and subsonic ammunition.

But they have so little energy that you cannot shoot hoofed game with them.

Is it possible to shoot with a silencer without hearing protection?

A silencer must reduce the sound pressure level by at least 20 dB(A).

It is important to know that a reduction of 6 dB(A) already means a halving of the volume.

Here are a few examples for better understanding:

  • In a quiet room you have a sound pressure level of 20-30 dB(A)
  • A normal conversation has 40-60 dB(A)
  • The TV at room volume has 60 dB(A)
  • A main road 80-90 dB(A)
  • In the disco (in the club) there is a jackhammer volume of 100 dB(A)
  • A commercial aircraft at a distance of 30m has 110-120 dB(A)
  • And a .308 caliber Winchester rifle shot at about 160 dB(A)

Hearing damage occurs when a sound pressure level above 120 dB(A) is applied for a short period of time and the pain threshold is between 130 and 140 dB(A).

So if the silencer lowers the sound pressure by 23 dB(A), which most silencers can do, it no longer hurts in the ears when shooting.

However, there is still the risk of hearing damage.

The hunting dog, which sits under the pulpit, is probably already far enough away to not suffer any more damage.

How heavy is a silencer

15 years ago, silencers were permitted as part of health protection in England and some (few) other countries on the basis of “Directive 2003/10/EC of the European Parliament and of the Council”.

At that time silencers had an average weight of 650g. Today there are silencers for large calibre weapons with less than 200g.

Is the muzzle flash reduced?

Yes, very much so in fact. In almost all cases, the muzzle flash is no longer visible through the rifle scope.

Does the silencer interfere with the optics?

A silencer with a diameter of 50mm can no longer be seen through the riflescope at a magnification of 4x or more.

Does the point of impact change when shooting with a silencer?

So far I know of only one case where the point of impact has not changed.

In most cases it changes between 2 and 10 cm.

Thicker barrels and light silencers change the point of impact less than thin barrels with heavy silencers.

Removing the silencer and putting it back on does not change the point of impact.

How does a silencer actually work?

The principle is actually simple.

The gases escaping at the muzzle are led into the silencer and go first into the expansion chamber where they can spread.

Then they are slowed down in differently designed chambers before they exit at the front, much more slowly.

How long does a silencer last?

I don’t know! A steel silencer probably lasts longer than an aluminium silencer.

I myself have fired more than 2000 rounds with an aluminium silencer.

You can see slight wear and tear from the hot gases.

But they are hardly measurable.

Does the silencer break down if you shoot too fast in a row?

Hunting sequences of shots are no problem for an (aluminium) silencer.

I have also seen a silencer in a shooting cinema, which broke because of a too fast shooting sequence.

On a military testing ground we once deliberately destroyed a silencer.

It sustained 100 shots within five minutes before it broke apart.

In the shooting cinema, when you see “continuous fire”, you will eventually see a strong flickering, which comes from the heat of the silencer.

To reduce this, there are protective covers.

Does my gun with silencer become top-heavy?

This question is asked very often.

Mostly in connection with whether the silencer is a hindrance in driven hunts.

A classic hunting rifle weighs at least 3.5 kg, plus the optics with 300-600g, which are located quite far back.

A silencer usually brings much less than 400g to the muzzle.

One says that it can “swing through” better and the other one is disturbed.

The silencer is not disturbing when sitting on the seat and if it bothers you during a driven hunt, you can shorten the barrel a little and compensate the additional weight.

Is it necessary to clean a silencer?

Do you wash your car? Yes! Do you clean your gun? Don’t say no now!

The fact is, the gun and silencer need care.

Powder residue settles inside the silencer and should be removed occasionally.

A cleaning rod or a cleaning cord are good tools.

If you can disassemble the silencer you can also clean the parts with a brush.

The gunsmith usually has an ultrasonic device to clean the silencer.

A light layer of residue, just like some oil, can even improve the damping effect.

Does the game react differently to a silenced shot?

Definitely yes!

Because the component of the muzzle blast is missing or greatly reduced, the game cannot perceive the direction the shot came from.

This often changes the direction of flight.

Especially with red deer I have observed that they even flee in the direction of the shooter.
