About the BCM® Standard 16" Mid Length ELW Complete Upper Receiver w/ KMR-A15 Handguard

All BCM® Upper Receiver Groups with a KMR-A Handguard Include:

  • One 3" Picatinny Rail Section
  • One BCM KeyMod Sling Mount

Manufactured by Bravo Company MFG, Inc. (BCM)

These Barreled Upper Receiver Groups are designed for shooting professionals and responsible civilians 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 and Upper 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 upper receivers 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, private security personal, and personal defense 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 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 or high quality personal defense ammounition. 

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.

    This thing shoots

    Tactical accuracy up to 1 MOA, this thing shoots. As expected, BCM quality although I cannot speak to durability/reliability over time, I’ll just have to trust the BCM name. Keymod is TOTALLY fine for the average shooter. I have knocked this thing around a bit, still no problems. From my experience, it’s a fairly flat shooter thanks to the expertise in mid-gassing. 10/10 recommend. Make sure you get good parts for the lower you pair with, as I was having some difficulty with light primer strikes until I swapped out the trigger with a stronger trigger spring. After that slight modification, the gun goes boom every time I press the trigger. No problems with BCM’s complete upper though, it was an isolated lower parts problem. If you’re worried about fine-tuning a build, I would suggest purchasing the complete rifle from BCM. I spent nearly $1300 at the end of the day on the build, so might as well get the complete rifle/pistol. Happy shooting, friends!

    BCM® Standard 16" Mid Length (ENHANCED Light Weight) Upper Receiver Group w/ KMR-A15 Handguard

    I have a Bushmaster AR15 with a M16 style fixed front sight a short handguard. So short that a verticle grip is the only comfortable option which works fine but I wanted more handguard real estate. The KMR-A15 is excellent and the Recce Upper is superb. Extremely accurate, excellent control with the Mod 0 Compensator and very happy to have the C clamp grip as an option now.
    Bushmaster upper now has a scope mounted for hunting and the BCM is my EDC with a red dot. At least until I finish eh build with a custom lower. Can't recommend enough.

    KMAR-15 upper

    This was my first AR-15 that I have personally owned. BCM came highly recommended. I’ve shot a few in my 45 years and I am pleased with what I have. It is very light in combination with hand guard. When I zeroed my husband. I was getting 1 MOA groups right away, with a proper bench rest. So far so good.

    Waffles; Light and Buttery!

    I had this fantastic new complete upper shooting center mass after nine rounds from BZO. I just got her out of the toaster and ran 300+ rounds with my red dot and 45's all day on rapid fire with little muzzle climb and light recoil. The 16" barrel is perfect for my long arms, and I can't wait to do some 500yd vibe checks on steel plates and see how she handles. The only thing missing is a bottle of Aunt Jemima!
