About the BCM® Standard 14.5" Mid Length EMWF Complete Upper Receiver w/ KMR-A13 Handguard

All BCM® Upper Receiver Groups with a KMR-A Handguard Include:

  • One 3" Picatinny Rail Section
  • One BCM KeyMod 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.

    Outstanding Upper

    I'm surprised more people aren't aware of this upper build. The medium weight fluted barrel balances the rifle perfectly. BCM comp works well. The taper shape and thickness of the barrel was exactly what I was searching for and it was under my nose at BCM the whole time. Shot about 300 rounds the first time to the range with this upper and was getting 1" 10-shot groups @ 100m with Hornady Black 62gr and 75gr as well as Hornady 55gr. Also likes Norma-Tac 55gr with ~1.5" groups. Winchester white box 5.56 55gr about 3-4" groups-- that's definitely the ammo, not the rifle. With an ACOG 4x32 I was consistently plinking a 18" diameter steel plate at 500yds and a 3'-wide bear silhouette @ 700yds. Lightweight, compact, barrel can heat up without throwing off POI, well-balanced. Very pleased. I appreciate all the stickers, magazines, posters and the hat-- BCM has made me a walking billboard lol!

    BCM 14.5" upper

    Outstanding workmanship, first 300 rounds without a single hiccup, exactly what I wanted and expected from Bravo Company. Keep up the great work! Oh, forgot to mention the "swag," thanks so much and that attention to detail keeps me as a "very loyal" customer!

    Beautiful Upper

    Completed my first ever AR-15 build with a Spikes tactical LPK, Magpul furniture, and this BCM Upper. Incredibly lightweight and a perfect snug fit. Flawless build and professional looking outcome -- I'm thrilled! I love BCM's key mod rail too...much better than the DD Keymod Slim rail with attachment points only at 3-6-9. I've got an ELW (non-fluted) upper on deck for build #2. Great job BCM -- quality products at an excellent price and made in the USA!

    Great Upper for Battle

    This upper is great for shorter ranges with maximum maneuverability. The medium profile barrel is great and it balances the rifle well, and settles it down when shooting freehand. Also, the barrel can take more heat than a lighter barrel.
