About the BCM® Standard 16" 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.

    Limited stock/. Barrel

    That was under the impression that the enhanced lightweight barrel was fluted I'm not sure if I got the right barrel . It says online if you look up ELW barrel from bravo Co it has fluted? Also I would like to order a number of other things but it seems to be that you guys are out of stock a lot but this is the second upper I have ordered from you guys and the first one was excellent .

    Amazing quality

    This weapon is exactly how they advertised it. Very light weight but doesn’t feel dinky whatsoever. The fit and finish is amazing and the BCG is true quality MPI full auto bolt. Nothing too fancy, mil spec. I don’t however like the rail, I don’t have any key mod products so I will probably switch that out instead of having multiple mounting systems. I like uniformity not necessarily knocking the key mod. So far I have gotten decent groups at 100 yards but have only punched 200 rounds through it with remanned ammo thanks to these shortages. Will post pics if this review lets me. Would be 5 stars if wasn’t for the key-mod and no charging handle. I felt like after spending 700+ on an upper that the charging handle would at least have a basic duty option that would come included. I ended up finding a bcm gun fighter from a guy at a local gun show. Fun fact, you can play baseball with this Upper it’s that solid.

    I already have a BCM upper that I love. However, this upper is blemished (the entire left side of the barrel). I still think I got a good deal but I am disappointed in BCM. They should have said it was blemished.

    Can't wait to shoot it!

    Haven't had a chance to shoot yet (should have my BCM lower in a few days) but so far I love it. Shipping was fast and the upper itself is amazing.

    My favorite non-SBR configuration!

    I have two of these 16" ENHANCED Light Weight *ALPHA* 13 uppers, and both will whack 12x18 inch steel all the way out to 600 yards every time I do my part correctly. I love the barrel profile - lightweight, but heavier where it does some good.... My oldest BCM upper has eaten 20,000+ rounds and the only issue I've noticed is the gas port seems to have gotten a little bigger (not a surprise). I have no reason to expect these won't be just as long-lived.

    Great quality

    I may not have the most accurate review considering I have only shot 200 rounds through this upper receiver so far. My cousin and I have both decided to piece our ar15s together. That being said, he went with some upper (ill update this if I ever figure out the brand he went with) his upper was around $230 after taxes and mine after including the bolt and charging handle was around $850. Funny thing, he made a joke about mine being so expensive and said it was just over priced aluminum and that our uppers are exactly the same... well, The differences are day and night... this Upper Receiver Group feels so solid. I swear I am sooooo glad I went with this vs a cheap upper!! When we shot our ARs man oh man lets just say you definitely get what you pay for on upper receivers.... This might not be the best review but for now this is my opinion. I will definitely buy again and recommend. I will make another review once I get a few thousand rounds through this thing.
