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 per Mil-Spec. 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 ENHANCED FLUTED UPPER MCM13 HANDGUARD

    The 14.5 upper is the best of both worlds in performance and no one does it better than BCM. The MEDIUM WEIGHT FLUTED is a great idea . The weight is just perfect!

    QUALITY

    Only one word needed, GUALITY. Excellent upper that is the perfect balance of wieght in my opinion. I went with the A2X after a ton of debating between the BCM comp and surefire warcomp. I plan on a suppressor and didn't want to be tied to surefire being the only option. There is a well known and recommended gunsmith 50 miles from me that will unpin and then repin and weld a new device for $55 when I get to that point.

    Excellent workmanship. Haven't gotten many rounds down range yet but all early indications point to this being one of my favorites.

    First AR Build

    Well actually it's the second but I didnt even fire a round through my first build before i bought a BCM 14.5 upper receiver. Took it to the range and after 500 rounds and no malfunctions I can say that this will not be my last purchase. I'm still new to the AR 15 world but BCM is definitely a quality company, in both product and customer service. Didnt expect the little extras that came with my purchase, thank you BCM. I cant wait to start my next buid.
    I did make a mistake and selected the Surefire SOCOM MB instead of the Warcomp but then I learned about blast diffusers.

    The perfect balance of portability and performance

    Let's face it, most of us don't need an HBAR barrel and miles of rails on our "up close and personal" carbine. For years I was a staunch believer in both, but this BCM upper changed all that. The barrel heats up more and faster than an HBAR, but not enough to make shooting uncomfortable at civilian rates of fire. The handguard is strong, lightweight, looks great, and has that excellent fit and finish feel. I'm generally with the "don't buy expensive gear just to please the marketing department - it's not making you a better shooter" crowd, but this rail is worth every dollar. Comparing it to a similar MLOK rail, the fit and finish make it far more comfortable to shoot. Light and handy, this upper brings the AR full circle to what it was designed to be: a lightweight, versatile, and capable personal weapon.
