About the BCM® Standard 14.5" Mid Length LW 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.

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.

    Amazing Barrel!

    I recently purchased this barrel after it was the ONLY ONE in stock since the Covid pandemic. Since then, I’ve come to love this product and am not surprised by how well it shoots!

    The Gold Standard

    Received my BCM 14.5" Upper w/ Battle Comp 1.5 pinned. It bolted right on my Noveske lower. The quality craftsmanship is very evident in all of their parts and I'll always use them for my builds.

    BCM lives up to their rep!

    This review is for the BCM® Standard 14.5" Mid Length (Light Weight) Upper with MCMR-13 Handguard. The upper shipped and arrived very quickly, which is great because I was really excited to get my hands on this. I installed it on a BCM complete lower I had purchased already for this purpose, making this a full BCM pistol. The fit and finish quality is very high -- I couldn't find a single tool mark or flaw in the finish. Everything was lubed from the factory. I've only had a chance to put about 100 rnds through the gun so far, ammo being scarce these days. The BCM trigger is excellent. Crisp break with good reset -- I'm not going to bother changing it out with anything better - the factory trigger will be great for duty and training use. The rail is lightweight and solid as well. I went with all BCM rail covers and foregrip for this one. This is a no-nonsense gun. I swapped out the safety selector for a Radian Talon and the buffer and spring for a JP SCS sense I don't have the A5 system. Beyond that, this gun will remain stock, and I'm looking forward to taking it on a trip to Thunder Ranch for an Urban Rifle course next month and sending a couple thousand rounds through it. REALLY GREAT GUN - One of my favorites in what is now a very large collections of ARs!

    First AR

    I had been looking to build an AR and take my time with it. However when this completed upper came in stock at the same time as the BCM completed lower well that sped things up. Two friends raved about BCM and being knew I don’t know shit. However this thing is a tank without being heavy. Solid sturdy and accurate I mean what else is there
