About the BCM® Standard 16" Mid Length ELWF Complete Upper Receiver w/ KMR-A13 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.

    BCM Upper

    The upper is amazing. The only problem I have is with the 4x4 ambi charging handle. The latch never releases when I pull it back on either side. It has to be a defective charging handle because I used an old one and it is perfect. It is defective. Will write BCM about it.

    BCM upper

    I already had the MCMR version and wanted a backup, but the Keymod version was the only one available. I just use the rail with a sling mount on the side and everything else attached to the top so in the end MCMR vs. Keymod does not matter to me. Excellent BCM quality.

    Awesome upper awesome Customer service.

    In short I researched and asked Bravo questions TONS of questions prior to purchase. They responded quickly, personally and on like every time.

    The upper shoots like a dream. Went out with a few buddies and was shooting 9 inch gongs using irons only like clock work. They had guns twice min in price and were asking to shoot it again time and time again. This upper is accurate, light and is all it was hyped to be. 1k% satisfied with my purchase and throughly impressed by Bravos customer service.

    Blew me away

    Amazing piece of hardware by BCM. As soon as I opened the box it instantly won me over. Fit and finish are of top tier quality not to mention all the extra goodies it came with. It's fair to say I got BRAVO fever

    Lightweight and durable

    As always with BCM, this product is really great - especially for the price. This upper is super lightweight and fantastic for AR that is going to be used as a close quarters to 300m gun.

    Quality and Lightweight

    Beautiful upper, barrel, and rail. Lightweight and rugged. The KMR speaks for itself. I put MOA holes consistently at 100 yards. BCM rocks.

    I've been wanting a lightweight, mid 16" minimalist build from BCM for a while. I picked up a complete BCM lower with the PNT trigger, VLTOR A5 extension/buffer with the BCM Gunfighter and needed an upper.

    The upper and BCM BCG, paired with the lower and small latch Gunfighter charging handle weighed in at 5.9 pounds before sights/slings/etc!

    I used a Vortex HST 4-16, to check accuracy before installing irons/RMR. I was getting 1.5-2 MOA at 100 yards prone unsupported (with a lot of wobble from me) with PMC bronze 55 grain (not exactly rock star ammo), so I know it will shooter better, because I know most of the spread on the groups was my lack of precision shooting skills.

    The mid-length gas system, paired with the heavier buffer was very soft. That could be in part with the BCM Comp (this was my first experience with it), which seems nice and didn't put off much blast to the sides.

    Cycles smoothly and reliably, accurate, and light! Can't go wrong with BCM!

    Another Outstanding Upper.

    This was my 2nd upper in two weeks from BCM. With a BCG and charge handle it came in right at 3 pounds. My goal for a ultra lightweight AR was met. Total platform weight with optic came in at 6 pound! Even better was the range report. Sub MOA with very little load development testing. I expect it to get even better as the barrel breaks-in. Could not be happier.
