About the BCM® Standard 14.5" Mid Length ELW 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.

    Bcm 14.5" mid length barrel and bcm bolt

    The barrel seems to be high quality as well as the bolt. I've ran a few hundred rounds through it and it's been a amazing product.

    Bcm 14.5" mid length barrel and bcm bolt

    The barrel seems to be high quality as well as the bolt. I've ran a few hundred rounds through it and it's been a amazing product. The only complaint I have is I ordered a complete upper and it didn't come with a charging handle. Seems for the 1100 dollars they would add a charging handle.

    14.5 Key mod upper

    I was jumping back and fourth between BCM & Daniel defense uppers, and I went with this one because it was a little cheaper and it ended up being a great decision. Not only was it cheaper but I believe it out performs a DDM4 I have. Great machinery work and awesome light weight barrel. I highly recommend any BCM upper.

    bcm 14.5 upper

    This is a top quality upper. Their upper has the tightest fit for barrel extensions I have ever seen. You need heat and a rubber mallet to get the barrel in. Their mil spec+ barrel has a nice, light contour. The KMR handguard is absolutely my favorite, and is professionally installed onto their very tight fitting barrel nut. Superb build quality, excepional parts quality. Professional grade all the way.

    Took an absolute beating

    I had recently swapped out a 16" standard profile BCM upper assembly with this one about a year ago to save some weight. Shortly after I took an a class that included a high round count coupled with muzzle striking and a few other shenanigans. I had concerns about the light weight profile of the barrel holding up to some pretty savage abuse. After about 1500 rounds and hours of striking 3/4" marine plywood I experienced zero POI shift. The pinned and welded A2X doesn't even show any signs of wear. The KMR-A heated up fast, but any handguard will with that much shooting. This is my 2nd of now 3 BCM uppers, I have zero interest in buy complete uppers from anyone else.

    Simply Amazing

    I got tired of building guns. Upper from these guys, barrel from those guys, etc. I wanted a rifle I could trust my life on, BCM was my first choice. I’m glad I spent the money.

    Always my first pick

    This is my second BCM upper assembly. They truly are as good as it gets. This is my first to use a BCM hand guard, I'm blown away. I've seen tougher hand guards, but not for this size and weight. The KMR feels very easy to get my hand around, and its fit and finish is perfect. The enhanced light weight barrel is no joke, too. That was my primary reason for replacing my old upper assembly.... I wanted a lighter barrel. The enhanced light weight didn't disappoint. The whole assembly points like a PCC or an SBR. The reduced weight makes the fin handle easier and my shoulder where the sling hangs has noticed too.

    I replaced a 16" standard profile BCM barrel and 15" DD SLiM hand guard for this... 14.5" enhanced light weight and KMR Alpha 13 and while it's less than a pound difference it feels like its 10 pounds difference. Best move I've made yet.

    Anything from BCM is quality and well worth the money. My only complaint is that you guys sent me a beanie. I live in South Carolina, I need a hat to show off my faith in your company.
