About the BCM® Standard 16" Mid Length ELWF Complete Upper Receiver w/ KMR-A15 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.

    It's Boring how reliable BCM is...

    I have had a REECE 14 for a few years, and was looking to get a lightweight well built upper to go with a lower I had assembled. While I have had nothing but great dealings with BCM, I'm not married to them, but after much research, I found
    that there was a lot to gain by going with BCM, and the only thing to loose was money. They had exactly what I was looking for , shipped it the next day, and when it arrived two days later I was pleasently unsuprised at the quality per dollar that I received. I'm not an AR snob, but Bravo Co. is making me a BCM snob.

    Awesome Upper

    The quality and attention to detail that BCM puts into their products really shows why they have earned the reputation that they have in this industry. I ordered this to go together with my BCM lower I purchased at work, the following weekend I took it out to the range and put some rounds down range and was able to get a few 3/4 inch groups at 100 yards. This rifle quickly jumped to being my favorite over my custom parts gun even though both shoot the same and have similar specs I just love the quality of BCM. I will continue to buy BCM products and plan to in the future for my brother who is a veteran and will be getting a BCM gun for christmas.

    Great Upper!

    Attached this upper to a lower I had complete a year ago and couldn't be more please. The whole system handled and shot very well. This complete upper was a lot lighter than I originally expected it to be and as an added bonus it looks great!

    EWLF Upper Assembly

    This is my second complete upper I have purchased from BCM. Very well assembled. You wouldn't believe the .6oz makes a difference but it is discernibly lighter. I installed this on an Anderson Mafacturing lower. The fit is so perfect you would believe the upper and lower were made by the same company. I am very pleased....."Bravo" on another job well done.

    Best Charging handle

    Build quality is as good as I expected. I always turn to Bravo when I need a part that I know will not be subpar.

    Lightweight and Awesome!

    I built a premium rifle and I wanted it to be as lightweight as possible. After researching all my options I chose the BCM upper with the enhanced lightweight fluted barrel and the Keymod handguard. It is awesome! As light as I hoped and it shoots outstanding as all BCM products do. I'll be using BCM on all the weapon systems I'm building in the future.

    The standard

    This is the 4th upper I've purchased from BCM, and as always, they are the standard I hold other uppers to! Great workmanship, quick delivery and nothing but the best!
