About the BCM® MK2 BFH 16" Mid Length ELW Complete Upper Receiver w/ MCMR-15 Handguard

All BCM® Upper Receiver Groups with a MCMR Handguard Include:

  • One 3" Picatinny Rail Section
  • One BCM MCMR 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. 

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 Mk rifle

    I have been fortunate to own many nice rifles, Robinson Arms, LWRC, Daniel Defense, Adams Arms custom and others. The thing that sets this rifle apart for me are the attention to every detail. You will not find a rattle or wobble of any kind on this rifle. Only reason it doesn't get five stars is that it doesn't have a stock ambi safety. You will never regret buying BCM.

    I have bought multiples of these uppers. Best out there, hands down!

    Great high quality upper.

    Looks good, solidly made. Free floated handguards and complementary muzzle devices should be the standard.

    This upper was surprisingly lightweight and transitions between targets extremely quickly. If anything, I almost thought it was too lightweight as I present the muzzle slightly higher than I would with any of my other AR15s. It takes some getting used to but this is now my new favorite upper

    MK2 BFH ELW Upper

    Great upper. I assembled it on an Aero lower with a MFT stock and ACT trigger. The weight reduction is very noticeable compared to a DDM4. Including the MRO and mount, the rifle weighs 6lb-9oz. The accuracy is comparable to my government profile barrels (BCM, DD, Colt) - "MOA-ish" 5 shot groups with good ammo. More importantly, the zero doesn't shift as the barrel heats up. Highly recommended.

    Functions Flawlessly

    2 days after purchase it arrived! I immediately took it out, cleaned and lubed it, then took it and shot 200 rds. I shot several brands and types. It shot all 556 and 223 I gave it. I also threw a mag or two of steel and it didn’t malfunction one time. Definitely something for when you NEED it. Love it!

    Amazing quality.

    I purchased an upper receiver about a month ago and decided last minute that I wanted to wait for the mcmr version. BCM was happy to take my return and promptly issued my store credit. I had to wait another 3 weeks to see what I wanted finally come back in stock but it was well worth the wait. They shipped out my order the very same day I placed it and I can NOT stop inspecting every detail on this upper receiver because I'm simply stunned at the level of craftsmanship. Handguard is way smaller than I anticipated and I love it.

    This will make s beautiful addition to any collection and I can't wait to get it to the range on my day off.

    Thank you BCM for working with me to help me get what I wanted!
