20-inch chrome lined bore and chamber, F-marked forged FSB, government profile, 1/7 Twist, 4150 steel barrel, Mil-Spec barreled upper


T-marked flat top with factory M4 feedramps by CMT


Proof loads for HPT and MPI - in progress


Barrel markings for 20" government profile by ER Shaw


M4 barrel extensions and M4 cuts in upper receivers for all barrels




Bravo Company USA have just released a new 20-inch government profile 1/7 barreled upper.

Features:

20 inch Chrome Lined Bore and Chamber
5.56 NATO
Government Profile (lighter under the handguards, like the USGI M16A2, M16A3, and M16A4 Rifles)
4150 barrel steel
1/7 Twist
T-marked Flat Top with factory M4 feedramps
Mil-Spec taller F-marked forged front sight base
All barrels are HPT (High Pressure Tested) and MPI (Magnetic Partical Inspected) per Mil-Spec.
Uppers are assembled, headspaced, and test fired

These do not include bolt carrier groups, charging handles or handguards.


I'm just doing it as a heads up for guys looking for 20-inch government profile uppers.

I'm in the middle of my middy project and I'm waiting for their 16-inch mid upper due out in Sept.

It's about damn time somebody did this as a standard order.  Special orders always worry me.

Group buys are sort of scary lately and Bravo is going to have one also in September for the release of their first profiles, 16" M4, 20" Government, 16" Govt Mid Length. But the difference is that they will always carry these products in their inventory, it's not just a limited run.

There will be a group-buy on the BCM 16" mid length barrels through Grant at G&R Tactical this Fall.

Also according to their noted Industry thread, starting in Q1 in 2006 new profiles will be available every 6-8 weeks. It will include 11.5", 14.7" with perm A2, 14.5", 10.5", etc. All with government profiles.

And then, Bravo Company MFG, Inc. (BCM) lower receivers are expected to be released mid 2006. I bet they won't get the deer head logo.

They're also stating that most of their components are from Stag Arms/ CMT which have a good reputation in quality.

There goes our money, darn BRD.

Can you confirm that the barrel steel used is 4150 and not 4140?.....
Is the barrel an ER Shaw barrel?

Are the uppers CMT?

TIA

These are 4150 barrel steel which is different from their previous 1/9 4140 steel uppers per the info from their website.

Here's Paul of Bravo Co.'s reply to my question:

"We purchase these contoured blanks direct from ER Shaw.

Our M4 upper receivers come from CMT."

Alpha-Romeo3, is Bravo doing the proof load firing themselves? I ask only because of the box of M197 rounds in your third pic.

Having seen firsthand while at Colt what can happen when a bad barrel get HPTed I'm going to fret and worry about this until you assure me otherwise

The Bravo boys are some of the best around. Please tell me they aren't doing this in-house

They didn't say if they're actually doing the proof load tests or if they're offloading it offsite.

When a barrel fails the test, is there a catastrophic failure, like the barrel blowing up?

I would assume the testing facility at the Colt factory is safe, they should fire those remotely.

All Bravo said was they HPT & MPI every barrel, I hope who ever is doing the actual testing take safety precautions.

A single proof load round should usually not be enough to cause a KB. What it will do is cause minute fractures(not visible to the naked eye) along paths of metallurgical flaws in substandard or weak barrels and bolts. These flaws would then be detected by the Magnetic Particle examination that follows the proof load testing. The barrel or bolt is then rejected if any of these flaws are seen.

I will not spend money on any new barrels or bolts unless they have been tested in this way.
Just not worth it, IMO.

Worthy of note is that German law REQUIRES all firearms produced or imported into the country to be proofed in a certified proofhouse in this way. Hence the esteem given the firearms produced in Germany.

Also worthy of note is that Bushmaster Firearms Inc., by their own admission, only spot-checks so many barrels from each lot the produce, and yet they rollmark every barrel B MP as if they had all been tested. Not illegal, but not 100% ethical in my book.

I extremely happy to see this trend happening. First Stag, now ER Shaw, and BCUSA is leading the way. Outstanding! Damn the torpedoes and let's make the unproofed barrel and bolt extinct.

Now I'll be able to sleep tonight. Thank you Sir.

Alpha-Romeo3, DR's description is spot on. In my time I have seen two catastrophic barrel failures during HPT. One of those would best be described as a burst/detonation, rather than a garden variety failure. A burst is very rare, but when it happens it's enough to make you change your shorts.

It was pretty scary to witness

I hope we see some changes in the law here in our country to proof test all barrels.

It's a good thing that I've always been a Mil-spec Kool-Aid drinker because I used to work for a military sub-contractor for about 15 years.

Wow, that must be exciting to see.

It's a good thing that Bravo Co. are taking precautions and I appreciate their dedication to provide the consumers with higher safety and quality.

That's why they are one of my top suppliers and I've been a satisfied customer.

+1 I agree, there are more choices now and great products like these are coming out.

To be fair with other BRD suppliers, Denny of GTS is also going to sell a mid-length 16" 4150 1/7 twist chromed lined barrel except his will have a medium contour which is slightly heavier than the government contour.

Talon Arms also have the Sabre Defence 16" mid-length 1/7 chromed lined barrel.

ABS have a new lower priced (group buy only) carbon fiber wrapped 16" CAR and mid-length barrels.

ADCO, G&R, JTac Supply and the other sellers are offering assorted barrels.

Nice choices but it creates another problem, which one to choose.

!/7 or 1/9 twist rate?

I've been told by some that the 1/7 will not sufficiently stabilize M193 rounds while others claim that they have had no problem...

As far as I know the 20" M16 barrels do not have the new M4 feedramps, but all BCM barrels will come with M4 feedramps.  Since we are set up to do it that way, we figured it would be just as easy and more desirable to include the M4 ramps on all models.

The complete barreled uppers will only be offered in flat tops.

Yup, they are currently built with Mil-Spec taper pins on the front sight base.  (also the GI semi-tub rivet for the front sling mount.)

thanks!

I've got one of the 20" BCM uppers. Fit and finish is fantastic. M4 ramps look great. Flattop is nice. Barrel has excellent park job. Chroming looks good. Flash hider indexed perfectly. Profile is right. A2 sight post with F-marked FSB all looks great.



For $399 it is hard to beat an upper with all the good features like 1/7, 4150, M4 ramps, etc....

1/7 twist stabilizes 55gr XM193 just fine. We shot 55gr M193 Ball on the range with our M16A2s from time to time, if M855 was not available for issue. Just as accurate if not more than 62gr M855, just a different point of impact than M855 with the same zero, about 3 inches lower @100m IIRC.

Anyone who tells you 1/7 twist will not stabilize 55gr projectiles is blowing smoke up your ass.


50 and 45 gr cartridges are not a good idea in 1/7 twist barrel however.
