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. These do not include bolt carrier groups, UNLESS selected from the drop down menu above.

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 world wide 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.

16" Upper Receiver Group with DD Lite Rail III September 22, 2016
Reviewer: Paul  
I am very happy with my purchase and the customer service I received when I had questions on the product. The package arrived quickly and undamaged. I tested it at the range with over 700 rounds and not one malfunction. Extremely satisfied with my purchase and looking forward products from BCM. I also appreciated the free BCM hat that you guys put in the box as well.

Thank you

Great product August 13, 2014
Reviewer: Dwight Kincaid from Kennewick, WA United States  
This is a great product. The only reason I give it a 4 star rating rather than a five is the fact that there were no grip covers included with my rail, holding the rail is like holding a cheese grater. My friend who recommended this product was amazed that they didn't include them with the upper. Paying $600 for an upper, you'd think it would be no big deal to include the rail covers.

NO BRAINER!!! May 3, 2013
Reviewer: David from IL. United States  
This was a no brainer for me. BCM has earned a good rep for their service and products. This is my 5th BCM build. You hear names like Colt , BCM , LMT , DD in the same context because they are proven to be dependable quality products. Spend the extra bucks and buy a PROVEN weapons platform!! Thanks guys.  P.S....thanks for the free swag!!!

Love it June 16, 2009
Reviewer: Joe from Maitland, FL United States  
everything I had heard about Paul & the BCM crew is true.  I've had nothing but positive experiences from my interaction with them, and the product is top-notch.  This upper is exactly what i was looking for (for my first build) and it is flawless.  I can't wait to get the last couple parts for my rifle and send some downrange
