Any interest is Tromix 450B Barrels/Bolts

Postby TonyRumore » Tue Dec 16, 2014 8:05 pm

Would there be any interest in Tromix 450B barrels and bolts?

It wouldn't take much for us to start cranking them out. The price would be the same as our 458 SOCOM set. $299 for chromoly and $324 for stainless.

Welcome to the Forum Tony.

I'm sure you will find some interest here.

We haven't even looking into the twist for the 450B yet, but for supersonic loads in the 50AE, 440 Corbon, 44 Mag, etc, we found 1:25 worked best with the short bullets that were available at the time.

What twist is Bushmaster using?

I think 1:18-20 would be just about perfect. What about bolts what would they cost?

Hi Tony. Thanks for offering the barrel/bolts. I'm more than sure you will be able to sell 450bushmaster parts based on your reputation alone. I also would have liked a 1:20 twist if that was available to me earlier. I know some guys are still interested in a mid length/rifle length gas system if it would be a no hassle drop in affair.
It shouldnt be too much of an issue for you seeing that you pioneered the SBS Saiga 12

I'm interested. Need a barrel and bolt but no one has a barrel. Prefer 16" midlength gas.

Finally decided to plunk down the $ for a 450 bushmaster upper and theyre all sold out! What gives?

I found some expensive and fancy uppers but they dont interest me. I like the standard cheap plain uppers, shoot just as well.

I considered building one but the parts are close in price to complete uppers usually.

Apparently they are built in small batches. I would call Walsh gun in caseville and ask about a timeline.

For the money I half considered one of those custom bolt guns by the gun store near lansing.

I need to build a 450 to demo Bowers cans.

I'll probably head over to the 458 forum to find a quality parts list.....

I have assembled and sold several dozen uppers with Tromix parts which IMO are superior to everything else.

Do they have dealer discounts?
Tom Bowers said the same thing about Tromix 450B parts.
I've only ever seen their Saiga stuff.

No Tony does not offer dealer discounts. His prices are very reasonable. The barrel/bolt combo is $250.


Coctailer

05-13-2016, 07:48 AM

Looks like its $299 for the combo.

I'll need one of those fancy upper receivers with 450 Bushmaster engraved on it also.:rambo:

Bowman's in brown city has a complete 16" Bushmaster .450 BM for $1100 I think.

Question, do you reload?

If yes (and you should for this caliber!) then build one, and go with mid-length gas system. Both the 16" and 20" uppers are carbine length systems, which I feel is over gassed but it works. IIRC, the 20" has an additional gas block installed at the mid-length location, but it's not operational. You can get more out of the mid length system when reloading, and factory ammo works just fine.

If no, then it really doesn't matter. I wouldn't pay over $600-625 for the factory upper, though. At that point, go with someone else; tromix, franklin armory, bartzman, etc. The Franklin armory is a 20" barrel with a rifle length gas system, which MIGHT be a bit under gassed when using factory ammo. However, I haven't heard of anyone having trouble with that, and I'm actually looking to build one with it.


HemiChallenger

05-24-2016, 06:52 PM

Thank you very much. I plan to reload. My idea was to use the cheap bushmaster upper otherwise its really not worth it for me. Making a bolt action sound better and better for this round...

An adjustable gas block would negate a fair amount of the difference between the carbine and middy gas ports.

Not sure if an adjustable gas block added to the cheaper uppers would bring the cost up above a middy...I've never looked at .450 prices or anything related. Just a thought...

I would think an adjustable gas block would be desirable, either way, in this sort of gun though.

An adjustable gas block is definitely a possibility. Which may work for hemi challenger.

Ive seen 3 diffrent guys who tried to build upper for FA parts that didnt go BOOOM without a lot of tweeking. Go see Scott at Walsh Gun Shop for an Upper or drop me an Email if your looking for a complete bolt action gun


Prices and sales tactics aside, Scott's quick stop has some uppers.

Could you elaborate more on the FA builds. I've been waiting for there 20" barrels to come back in-stock for a build.

I have sold a lot of 450BM since last fall. My build is designed to be LIGHT since it is a hunting rifle. The factor BM and most of the assembled uppers are just pigs! The factor BM weighs about 10lbs. They all use the bull barrels with .936 gas blocks and the heavy Hogue tubes. My builds are based on the super light and accurate Tromix 18" 1:28 barrels with the .750 middy gas block. I use a Seekins 12" or 15" rail and MFT stock which puts the rifle right at 5.5lbs without optic. They cycle perfectly with the Factory Hornady ammo and are super accurate. Some of my customers are getting sub MOA at 200 with the 250g FTX ammo.

So if you want to do it right don't waste your money on the cheap uppers or the factory rifle. Get the Tromix stripped upper, good BCG, lightweight rail and the Tromix barrel, bolt and brake combo and your good to go. Tromix sells the upper with the opened ejection port for $125. The Barrel and bolt is $300. The excellent brake is $60. A Seekins MCSR rail is $160. Add a $90 bolt carrier and a BCM Gunfighter and your at just under $800 for a kick ass upper that will shoot inside a quarter at 100 and drop any whitetail at 300 with confidence.

Thinking about another 450, tromix concern

Postby Bmt85 » Thu Nov 10, 2016 3:00 am

So I have a factory 16" upper and have no complaints so far. But I really want to build one, because I'm 6'4" and prefer 18-20" barrels, and I want a longer than a carbine gas length. I've been watching for Franklin armory to get there 20" rifle gas barrels back, but it's been almost a year. I think I narrowed it down to tromix or gryphon. However, I have a concern with tromix. They only run a light weight profile, which is great, but the barrel diameter is only .785 after the chamber. So roughly .167" thickness of metal from I.d. to o.d., which does not give me a good feeling, especially because I reload and plan on leaning it. So am I overthinking it, or should I be concerned?

She carefully stood on him, and placing one leg on her broad chest, and the other on the stone muscles of the abdomen, froze, as if pondering further actions.
