Professional Grade Weaponry, by BCM®
Made by Bravo Company MFG, Inc. (BCM) These Barreled Upper Receiver Groups are designed for shooting professionals with the Mil-Spec features for the demands of their duty. They are fully assembled, headspaced, and test fired.
As a note: BCM barrel components are parkerized separately before assembly. Prior to shipping, all BCM upper receiver groups are test fired for function, laser bore sighted with a Milspec carry handle for sight alignment within Mil-Specs, and then batch samples are test fired for accuracy. As such, the upper receiver group will show handling marks consistent with these quality control procedures.
M4 Feed Ramp Barrel Extension
M4 Feed Ramp Flat Top Receiver
In developing the USGI M4 carbine as one of the primary weapons for today’s infantry, some modifications were performed to the original M16 platform to enhance the reliability of the shorter barreled carbines. With the shorter carbine gas system and the increased gas port pressure, the carbine cycled faster, and at times the cycle rate could be faster than the magazine would feed ammunition. One of the modifications done to increase reliable feeding included enhancing the angle and the length of the feed ramps. This USGI modification was done to both the barrel extension and the upper receiver, creating a longer and steeper feed ramp. These Mil-Spec M4 feed ramps are part of the original CNC manufacturing process. As a result, the factory machined M4 feed ramps on the receiver are hard coat anodized which adds significant strength to the aluminum. This feature is offered on all BCM uppers and all BCM barrels.
T-Marked Upper Receiver
The contemporary M16/M4 rifle is built around the concept of modularity. All of the BCM flat top uppers feature a USGI type laser etched T-marks to provide addressing for the remounting of tactical accessories such as optics, laser sights, etc. This enables the weapon platform to be easily configured and then accurately reconfigured for each specific mission.
USGI 1/8 Twist Rate
The USGI 1/8 twist rate of all BCM Stainless barrels is the preferred twist rate by the DoD and most professional infantryman. This twist rate has proven very versatile and can effectively run the new heavier 5.56 ammo that is hugely popular with military and private security personnel for its’ superior ballistics.
Mil-Spec SS410 Barrel Steel
This 18" BCM barrel is machined from SS410 stainless steel. Featuring hand lapped 1/8 twist rate button rifling and M4 feed ramps barrel extensions, the 410 stainless barrel gives the shooter the best balance of weight and accuracy. 410 stainless is also harder and more corrosion resistant than conventional 416 stainless found in other precision barrels
5.56 NATO Chambers
The USGI 5.56 NATO chamber is the best choice for effective deployment, reliability, and compatibility, of higher chamber pressures of military ammo.
Government Barrel Profiles
Duty rifles are built to be carried - day in and day out. The USGI barrel profiles (often referred to as the Government Profile) enable the operator to carry their weapon for longer periods of time and deploy them faster than the heavier commercial H-Barrel counterparts. The government profile barrel is also compatible with the current M203 mounting systems.

Response to Review Request July 22, 2019
Reviewer: Mark Walker from Central Point, OR United States  
Paul,

I am happy with the product I received. The build is not yet complete so I cannot yet say everything is perfect.

I can say I will do business with Bravo Company in the future.

BCM SS410 18” Upper June 4, 2019
Reviewer: Gabe from Tinker AFB, OK United States  
The upper shipped to me real quick along with extras that I didn’t know came with it! It came with a BCM magazine/catelog, BCM beanie, stickers, and some lube. The upper actually ran really well and I had no problems with it. This was my first time ordering from them and now I can’t see myself switching to any other company.

Excellent Quality and Lightweight June 4, 2019
Reviewer: Ray from Fayetteville, NC United States  
Very lightweight for what you’re getting. Put it on my lower and the gun naked weighs 7 pounds. When I added a 1-4 Leupold vx-r, one-piece mount, MBUS, inforce light, the included keymod sling mount and a bcm KAG, the whole package weighed 8.5 pounds. Great for a midrange gun that I can still CQB. Or could push out past 300m with better glass. Love it.

Upper half May 8, 2019
Reviewer: Joe from Tukwila, WA United States  
Zeroed out with a Nikon p223 3x with 62gr 5.56 surplus ammo, 1 MOA all day!   My educated guess would be sub MOA with better ammo.  I’m hooked on BCM, if I could spare the change I’d pickup their newer ELW complete upper in a 16” middy.  Also gotta put a plug in for the KMR alpha rails..... still the best on the market!
