About the BCM® Standard 14.5" Mid Length 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.

    14.5 inch M Lok upper with BCG and charging handle.

    Bang! Bang! Bang! I fortunately get to shoot for a living. I’ve wanted to try BCM for years and now I can say my other AR’s are going to get dusty. Even running this equipment EVERY day and it has performed flawlessly! I will own more!

    Except product just as expected. BCM’s reputation speaks for itself. If you are on the fence about purchasing, don’t overthink it. Great product.

    Upper receiver

    I can’t believe I’m leaving a review for something that everyone on earth knows is top notch. I consider myself lucky to have ordered my upper before BCM was clean out of inventory. I plan on ordering another as soon as they are available.

    Greater than I expected

    I was told bcm was a great company to own. I sought out owning a particular rifle from them and dispite the large demand within our country right now and limited stock. Bravo company wrote me an email explaining their shortage and how I can attain their product. This took several months of waiting, but eventually an upper in the length and style I wanted became available. Delivery was fast and accurate. Taking this to the range the only word I can use to describe it was smooth. Its extremely noticeable when firing the rifle that it performs the way you would expect it to with their reputation. Great

    Top notch middy upper

    The BCM mid length upper receiver group with MCMR -13 Handgaurd is built like a tank. Mounted to a BCM Lower make one heck of a Recce rifle. Follow up shots are smooth and right on target. I now have a new favorite weapon and BCM fits the bill 100%. Looking forward to do a few more builds for my job.

    Couldn’t be more pleased with the quality and performance of this upper. As soon as I opened the box I was shocked with all the extras that came with it including magazines, a hat, Magpul QD sling mount and stickers. Plus the oil it comes coated in smells awesome !

    BHF or BFH. Should be called BMF!!! Best upper I’ve ever owned. Mod 1 comp controls recoil and muzzle rise allowing for super fast and accurate follow up shots. Just ordered a complete rifle after using this upper. Amazing quality, fast shipping, and good price.
