Bravo Company builds:  Life Saving Tools™
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.
Featuring BCM’s Patent Pending MK2 Upper Receiver
This proprietary design offers enhanced rigidity over the USGI product.  The increased rigidity limits barrel deflection which aids in consistency/accuracy.   Less flex also reduces premature damage, wear, and failure of bolt lugs from misalignment.   A gas expansion chamber is machined above the charging handle track, combined with dual vents machined at the rear (each side, above charging handle latch) help to redirect and vent gas away the shooters face. 

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.

    Piece of Art!

    Have wanted a BCM rifle for a long time. The craftsmanship isn't comparable to anything I've encountered in my years of shooting

    Have been wanting a BCM Upper for some time now as I consider it the standard for those serious about craftsmanship you would bet your life on. I was like a kid on xmas morning when it arrived. Everything about it screams perfection. Thank you BCM!

    Mk2 lightweight 14.5 upper

    What can I say? Perfect. Fit on my lower is snug. The mk2 receiver is an interesting weight savings, and the rail actually tabs into the top of the upper so I’d be confident in retaining zero with irons. The pin on the mod 1 comp is noticeable, which I prefer. Lightweight and seemingly very durable. Quick delivery, too.

    BCM MK2 14.5” lightweight mlok upper

    What can I say? Perfect. Snug fit on my lower. The mk2 upper receiver is really an interesting weight savings, and the rail system actually notches into the receiver, so I’m not worried about losing zero with good irons. The pin on the mod 1 comp is noticeable, which I prefer. Exceptionally lightweight and seemingly durable build.

    Great upper!

    This is my third BCM upper, first slim rail. My primary rifle was a BCM 16inch mid, with a 9inch QRF rail. Great upper. I wanted to try a slim rail, so I purchased this upper. The weight difference is pretty amazing. I also did not think 14.5 would make much difference over a 16inch. Well it does. It is much "handier" in so many ways. The BCM M-LOK rail covers are fantastic as well. It give the upper the same grip texture as my M&P 2.0 pistols.

    BCM quality, fit, and finish is top notch. I highly recommend their products. Made in the USA and by a veteran owned business. It simply does not get any better.

    Great upper!

    This is my first AR, and I was told by a friend to only go with Bravo. Once I received the upper and lower, it made sense, and I will only be buying my future parts from Bravo. Great job guys! Keep up the good work.
