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 1/7 Twist Rate
The USGI 1/7 twist rate of all of the BCM barrels is the preferred twist rate by 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 personal for its’ superior ballistics.
Mil-Spec Barrel Steel (Certified Mil-B-11595E)
BCM barrel steel is Mil-Spec per MIL-B-11595E, and is independently certified. This grade (CMV) of steel is a Mil-Spec steel used in the USGI M16 family of rifles; it is stronger and will last longer than the typical barrels offered in the commercial market. This Mil-Spec grade steel gets its’ additional strength and rigidity from an increase in carbon and/or vanadium in the alloy. This will offer increased barrel life and performance through use in all types of extreme environments and temperatures.
Chrome Bore and Chamber
One of the first modifications that were made to the original M16 in the mid 1960’s was the addition of the chrome lined bore and chamber. It is now a worldwide standard in the industry for a battle rifle. The chrome bore and chamber is harder than the barrel steel and on the USGI M16/M4 rifles will aid in chambering, extraction, and reliability. It increases velocity, and also resist against fouling and corrosion from extended use in the field. This gives the end user a longer barrel life with less required time in maintenance and cleaning.
Manganese Phosphate Barrel Finish
Barrels are parkerized with the manganese phosphate finish (Mil-Spec A-A-59267). Military specifications also state that the entire barrel surface is phosphate finished to create a porous surface to absorb oil as to resist against corrosion from the elements. BCM barrels are phosphated before installation of front sights. This is a much more extensive assembly operation, but insures that the entire barrel is finished and protected . . .even under the front sight base.
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.
HPT / MP Inspected Barrels
Military specifications require that barrels undergo a HPT (High-Pressure Test) load as a part of quality assurance procedures. Commonly referred to as a proof load, the M197 HPT is rated for 70,000 psi. BCM barrels are proof loaded and then MPI (Magnetic Particle Inspected) to detect any possible flaws in the barrels surface. The barrels are MP inspected with both circular and longitudinal magnetic fields per ASTME1444-01 (current Mil-Spec) to assure a high quality finished product. All BCM barrels are marked HP MP as our proof load marking.

Reviewer: Muss from Marion, OH United States  
Ordered a mid-length upper and a couple accessories. Packages arrived in two days. Great finish and quality on the upper, lightweight rail. Happy with the purchase. Have since ordered more parts and the shipping was fast. Will but again.

Damn son April 9, 2019
Reviewer: Curt from Texas  
I wanna say so far I am nothing but absolutely impressed with these guys and the products offered. Top notch fit and finish and they really go above and beyond with packaging and the inclusion of magazines, qd slots and rail panels etc. (let’s not forget the badass hat). The experience online was pleasant and straight forward and was shipped out promptly. I’ve only put about 500 rounds through this upper so far but I’m in love and have no doubts that it is a reliable product and is without a doubt an excellent and accurate barrel. Extremely flat shooting and the addition of the gunfighter comp really keeps that muzzle rise down. This really is a great product. I can see myself building rifles exclusively off BCM uppers from now on and will highly recommend this product and company regarding any new AR15 build. Great job. Extremely impressed thus far.

Business as usual April 9, 2019
Reviewer: Shark from Richmond, VA United States  
Bravo:
Fast processing, faster shipping, upper lined up and squared away.

Upper:
Light (for a 16" gov't profile especially), feels good in the hands, functions as you'd come to expect from a BCM upper after just under a case of ammo through it.

MCMR:
LIGHT. Rigid enough assuming you don't mistake it for a speed bump or axe. M-lok stuff mounts to it solid. Feels good in the hands (coming from a stubborn 1913 rail or plastic hand guard only guy).

Barrel:
Groups like it should for a standard, non-SS barrel. Arguably better. 77gr OTM was grouping 1.1-1.7 MOA at 100 yards from a solid rest. It'll out-shoot a majority of folks in the hands and on the shoulder.

Verdict:
If you're looking for light light lightweight grab the MCMR with a LW or ELW profile barrel. That would be a scary feather like combination. I already have more LW and ELW than I need so I decided to give gov't profile another run.  Solid upper from solid people doing solid work. I can dig it.
