About the BCM® Standard 14.5" Mid Length ELWF 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.

    Quality/ light weight

    This upper is exceptionally well built, it is also very lightweight. Shoots great and very well balanced.

    As good as I could have hoped

    I cannot say that I am an expert in such things, but this upper is more than I would have hoped it would be. It feels just as light as my 10.5" gov't profile upper, but with a better balance and obviously better ballistics. Feels just as maneuverable. Accuracy is great, as far as I can tell; it hits what I aim at so long as I do my part, but have not pushed distance really at all. Love the handguard size and shape and seems tough enough for my purposes. This is currently sitting on an Aero M4E1 lower with my favorite-so-far furniture, nothing super fancy, but this is my go-to rifle and I do not anticipate needing/wanting to purchase a new 5.56/223 caliber for the foreseeable future. Actually, since I got this, I have been wanting to switch calibers on my 10.5" from 5.56/223 to 300BLK as I have not been shooting it in its current configuration since I picked up this BCM upper. The only thing I wish was available from BCM was more in-house options for muzzle devices when purchasing, but that is nit-picking and not a knock against the quality of this product.

    Bcm upper

    Been looking for bcm rifle for a full year, ordered a 14.5 upper Friday morning, Found a bcm lower magically in town Friday evening. Being a new gun owner had a friend help me zero in a red dot. Shot it today! I could not believe how tight the groupings were with this rifle. I’ve spend the last year on line researching the reviews of BCM rifles. They truly live up to there reputation! Super happy with my upper and rifle , absolutely love it! Awesome job BCM!!!

    14.5 mid length

    Put this upper on a Spikes lower with the A5 buffer system installed... dead air Sandman L... it feels like a .22. Without the can it’s one of the lightest setups I own. Always wanted a BCM upper. Glad I did it!

    Best rifle for your worst day!

    14.5” pinned and welded is the added CQB element without giving up extended range accuracy and is a non-NFA item. I work in law enforcement and chose this weapon for my off duty SHTF weapon. Highest quality item without paying ridiculous prices. The company has a solid long standing reputation but they have exceeded my expectations in regards to customer service requests and problem solving. I am so impressed that I’ve proposed changing all our patrol rifles to BCM! If it’s in stock, just get it. You won’t have buyers remorse!
