About the BCM® MK2 BFH 16" Mid Length 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.

Featuring BCM’s Patented MK2 Upper Receiver

This proprietary design offers enhanced rigidity over the USGI product.  The increased rigidity limits barrel deflection which aids in consistency/accuracy.   Less flex also reduces premature damage, wear, and failure of bolt lugs from misalignment.   A gas expansion chamber is machined above the charging handle track, combined with dual vents machined at the rear (each side, above charging handle latch) help to redirect and vent gas away the shooters face. U.S. Patent Numbers: 10670355, 10677549, D888182

Cold Hammer Forged Barrels

This process of manufacturing barrels has been used for European small arms for generations, and it is gaining popularity in the United States because of the increased barrel life and outstanding accuracy of a hammer forged barrel. The BCM BFH series of barrels are made right here in the USA. (Just like all the BCM products.)

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. 

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.

    MK2 BFH 16" Mid Length Upper Receiver Group w/ KMR-A15 Handguard

    With an RRA complete lower sitting alone for some years, I finally decided to finish the build. This is my first AR build, and I could not be happier with the decision to go with a BCM upper. The upper I chose was out of circumstance as it was one of very few still in stock and with everything we’ve been seeing in 2020, I didn’t want to wait much longer, so I bit the “bullet” and took what was available that best matched what I wanted. I thought I must get the M-Lok guards, but truth is, there is plenty of K-mod accessories out there that you’re not left wanting. I have Zero complaints. The upper feeds and shoots with grace and precision. Being a lefty, I opted for the Gunfighter 3x3 ambidextrous charge handle(love it, perfect size), also added a set of Troy fixed battle sights, a Sparc AR red dot(perfect 1/3 co-wit setup), Magpul ACS-L stock and Magpul AFG2 fore grip. Ordered recently a BCM mod1 pistol grip, and plan for a Streamlight unit up front finishing off a perfect build for myself. Back to the point of the review; the AR market is now flooded with suppliers, I have to believe BCM to be one of if not the best place to shop for your AR needs, hands down, impressed and greatly satisfied.

    Purchased along with bcg and charging handle. Nice tight fit with a spikes lower. Super soft shooter with great accuracy. Not in any way dissapointing other than not getting a free hat or shirt on a 1000 dollar purchase. Overall well worth the money and was shipped super fast. Great job BCM.

    MK2 BFH 16" upper

    Great accuracy. Light. Reliable. This upper replaced a LWRC piston upper that was just too heavy and didn't meet my accuracy standards. Love it.

    MK 2 upper

    Wow did this upper go perfect with my lower. I had purchased a BCM rifle a few years ago it is the Mod zero which is their basic carbine. This upper was just to up grade my BCM rifle I paired it with a Vortex razor hd E 1-6 and once zeroEd it was easily slapping steel at 300 and 400 yards . It holds a really tight group sub minute .
