All BCM® Upper Receiver Groups with a MCMR Handguard Include:

  • One BCM MCMR Sling Mount
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. 
Cold Hammer Forged Barrels
This process of manufacturing barrels has been used for European small arms for generations, and it is gaining popularity in the United States because of the increased barrel life and outstanding accuracy of a hammer forged barrel. The BCM BFH series of barrels are made right here in the USA. (Just like all the BCM products.)
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.

    amazing quality.

    When I picked up the box, I thought it was an empty box. Then when I opened it, I was amazed, on the how light this upper was. Also I could feel the quality of the parts. I'm very happy with this.

    Great upper

    Bought this and a few other things for a new build I'm doing and, although I'm not done, everything is of great quality and I'm very happy I decided to go with bcm. Keep up the good work, folks.

    Awesome Product

    I am really liking this upper from BCM. Paired with my BCM lower and the VOLTR A5 system, it is a supper soft shooting gun. The rail holds up very nicely with all my attachments. I only have a few hundred rounds through this upper but I do not have any complains (besides the upper being in such high demand). The MK2 upper receiver weighs the same as a milspec upper but enhances durability and functionality while being optimized for use with a suppressor. This is a quality product that you can depend on with your life. You will not be disappointed. Get yourself one ASAP.

    Great upper use a heavy buffer

    Great quality and craftsmanship, fast shipping would buy it again. I would recommend that you install a heavy buffer with this upper, I had a standard 3.0 oz buffer and the casings we ejecting at 3 o'clock and jumping back to me (shooting in an indoor range). I am using a KVP 4.3 oz and things are much better now. The casings are ejecting at 4 o'clock and recoil has diminished noticeably.

    First mk2 receiver I’ve owned and it’s impressively solid. The pin job is very well done and weld is clean. Just visible enough to make it known that it’s a permanent attachment. Very accurate barrel, I haven’t yet found what it likes to be fed but have yet to find something it won’t eat. Super pleased with the quality I’ve received.

    Upper Reciever

    Always heard about BCM quality, fit and finish but now I understand why they're considered one of the top tier Firearms. Received in perfect condition and very satisfied. Recommending to the rest of my 2A friends

    14.5 elw mk2

    This upper is lightweight while still maintaining a lot of rigidity. The mk2 upper makes left handed use much easier with the position of the forward assist and the whole less flexing of the receiver makes a lot of sense. I haven't patterned it yet but it seems very accurate and the quality is about as good as you can get. Very happy with it.
