Made by Bravo Company MFG, Inc. (BCM®™) These Barreled Upper Receiver Groups are designed for shooting professionals 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 & Flat Top 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® uppers 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 and private security personal for its superior ballistics.

Mil-Spec 11595E - Barrel Steel

BCM® barrel steel is Mil-Spec per MIL-B-11595E. 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. The 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 on the USGI M16/M4 rifles 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 ammo.

Mil-Spec F-Marked Forged Front Sight Bases

Mil-Spec for rifles issued to the troops require taller front sight bases on all flat top AR rifles. Many commercial offerings use M16A2 height front sight bases on all of their barrels regardless of what type of upper it is installed on. As a result, owners of rifles and carbines with the flat top receiver configuration can have problems getting a proper 'zero' for elevation with Mil-Spec back up iron sights. As all of the BCM® uppers are built for flat top uppers, all have the proper Mil-Spec F marked front sight base to insure the correct height for iron sight zeroing when using military iron sights. Mil-Spec taper pins secure the forged front sight base with the sling swivel secured by tubular rivets.

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.

    Excellent Product!

    This barrel and upper receiver are a great combo! If you're looking to build a custom M4 replica, this is a great option. I couldn't be happier with how mine turned out. I bought a Magpull Mid-length hand guard in stealth grey to match my lower with Magpull furniture in stealth grey as well. The gun turned out looking very nice and shoots even better!

    Precisely built and accurate

    i replaced an upper from another manufacturer. It only cost half of what the BCM 16" LW cost and it looked good. But upon shooting it I found it would not zero properly and groups were large. The BCM LW upper was shot for the first time this past Sunday. It produced groups half the size of the other brand. Instead of having a sight cranked all the way to the left to get a 25 yard zero, the BCM allowed the rear sight to be centered. I am no longer going to buy the other brand. This is my 4th BCM upper and they all perform well.

    Great quality. Great price.

    Got a bcm mid length lightweight. Like it a lot. Worked great with wolf and m855 and everything else I could find. Managed to melt the handgaurds (they were del ton spares I had) which I haven’t done ever in years of shooting. Changed it to a free float Troy battle rail.

    The rear pin came out in 2 hits with a hammer and punch. Front pin took about 90 hits to remove. Unsure why. Never been that hard to remove any other front sight base before.

    Great customer service. Next time I’ll ask to have the pins not installed before I order.

    Thanks for making a reliable excellent product at a competitive price. $440 for a mid length pencil upper chrom lined minus bcg is a good deal in my opinion. I put a colt bcg and colt charging handle in it. On a spikes Lower with colt lpk. No issues so far. Recoil was more than my 10.3 pistol so I will try an H buffer.

    Bravo Company Convert

    I had been avoiding replacing my current patrol carbine, until this item came up on sale. I replaced my upper and used the Bravo Company hand guards. I can't believe how much lighter the upper is compared to my Armalite Carbine! The finish and craftsmanship is beautiful on this upper. I was so impressed with the upper and ended up buying a whole new rifle setup from Bravo Company! Nice job guys! You have gained a customer for life!
