About the BCM® MK2 BFH 14.5" Mid Length ELW Complete Upper Receiver w/ MCMR-13 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.

    Incredibly impressed

    Initial impressions are that this upper is of extremely high quality. Fit and finish of the parts is impeccable. It is aesthetically beautiful and shoots incredibly softly. The ejection pattern is perfect and consistent at about 3:30. Seems perfectly gassed.

    After shooting various types of ammunition, I am super impressed with the accuracy. With PMC Bronze .223, Winchester White Box 5.56, and M855, it consistently shoots approximately 2" groups at 100 yards.

    Next I tried some Frontier .223 55gr FMJBT and the rifle LOVES it. Shoots consistent sub-MOA groups at 100 yards with a red dot and 3x magnifier. This is NOT match ammunition, and I feel like I am the limiting factor to accuracy at this point. Need to get more magnification and see what it can really do.

    Everything about this upper is top tier. It is better than any AR-15 type rifle that I've ever shot.

    Good choice

    Great upper, low recoil even with the A2x. MK2 is very aesthetic and functional, plus it came smelling fantastic (100% serious). Highly recommended.

    First AR Build

    Great product. Shipped fast with tracking. I had to piece together an AR which is great because I'm learning how simple these are to build.

    Wish there was more beginner info on the pages. I didn't add the charging handle and now I'm waiting anxiously for it to arrive.

    BCM MK2 BFH 14.5” mid length Enhanced Light weight upper

    Outstanding quality, with perfect machining. Excellent fit up with my lower, nice and tight pin alignment. Barrel feed ramps are perfectly aligned as well as the hand guard. I highly recommend BC products and I’m already planning my next build using their products!

    I paired this upper with my aero lower and it is a perfect fit. I ordered it with a mod 1 permanently installed and I think it’s one of the best fire arms purchase I’ve ever made in my life. Went to order and they’re already sold out and I’m not surprised at all by that bc it’s such a great product. If you can order one, do it, you’ll be glad you did.

    BCM® MK2 BFH 14.5" Mid Length (ENHANCED Light Weight) Upper Receiver Group w/ MCMR-13 Handguard

    I want to start by saying I am just an average recreational shooter, and very amateur rifle put together-er. I am former Marine Corps (2531/0621, 20 yrs ago) and while I have a little time behind these types of weapons, I am by no means an expert or high speed operator.

    All that being said, this upper is easily the lightest weight and smoothest operating upper I have been exposed to.

    Shooting "green tips" and using sand bags as support I was able to hold a 2" group at 100yrds, with a x4 ACOG, and it fed every type of ammo I had on hand, with no issues.

    Everything operated smoothly, and it never felt like it was hanging up or resisting in anyway.

    Its my first BCM upper, and I wouldn't hesitate to recommend them when they are in stock.

    Highly Recommend!

    This upper is a beast! Feels amazing! Very streamlined and well balanced. The quality is second to none. BCM has become my go to! I have no plans of buying anything else. Waiting for a few more of their uppers to come back into stock

    Only gave four stars because I haven’t had it to the range yet. But it is by far the best quality upper I’ve bought. If your thinking about it just buy one.

    14.5 m-lok upper

    Cannot say enough about how impressed I am with this product. I never would’ve guessed the box it came in contained a complete upper with bolt and charging handle. The weight was nearly non existent. The look and feel of this beauty is just amazing. And the smell lol, it smells great too. Can’t wait to finish my set up and rip of few down the barrel.
