Professional Grade Weaponry, by BCM®™
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
M4 Feed Ramp 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.
Government Barrel Profiles
Duty rifles are built to be carried - day in and day out. The USGI barrel profiles (often referred to as the Government Profile) enable the operator to carry their weapon for longer periods of time and deploy them faster than the heavier commercial H-Barrel counterparts. The government profile barrel is also compatible with the current M203 mounting systems.
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.

    I’ve Purchased 4!

    Posted by George Azar on Aug 15th 2021

    Bravo company has produced some of the best products I’ve purchased and this 1 is no exception! I’d been wanting to produce a M4A1 SOCOM civilian clone and this upper has definitely enabled to do just that! I loved it so much this has now been my 4th SOCOM to purchase from BCM!
    Thank you for not settling for average but to produce an excellent quality gun!
    As a side note, I’ve also purchased 2, 11.5” uppers and waiting for the right 12.5” to become available.

    Nice upper, need to work on timing of muzzle device

    Posted by RobMa on Jul 14th 2021

    Nice upper like usual, my only qualm is the same as before when I had something pin and welded. They can’t seem to get the fh timed correctly before they actually do the weld…
    Other than that it would otherwise be another five star rating…

    BCM® Standard 14.5" M4 (SOCOM) Upper

    Posted by MARK HIGHWAYMEN on Jul 4th 2021

    Can feel and see the difference in fit and finish compared right away to other premium brands. It feels better than Colt these days and feel confident with the quality controls BCM has in place. 550 rounds in so far and runs smooth BCM bolt carrier
    and with BCM Comp Mod 1 to give good recoil impulse and very low muzzle rise. I just love the way this weapon feels firing it. I feel very much I could depend on my life one it. Its my new favorite rifle and cant wait to go shooting the next time. Thank you BCM for being as good as your are and trying to stay as affordable for us average Joes wanting quality without taking a second mortgage!!!

    SOCOM upper

    Posted by Fantastic upper on Jun 29th 2021

    Easily the best upper I have ever purchased. if you plan on removing the gas block and barrel nut yourself to install diff rails other than the kind this supports, (I went with Danial Defense RISII rails), be prepared for some serious work. Punch Pins were really in there and it took a breaker bar to get the barrell nut loose. However, build quality is superb and I will never buy an upper from anywhere else again.

    standard 14.5" M4 SOCOM URG with A2X

    Posted by Some guy in Texas on Jun 28th 2021

    All the great fit and finish you expect from BCM. Loses a star because it's actually 14.75" not 14.5. The reason I ordered this instead of other models was to have a correct 14.5" barrel and not a goofy stretched barrel. It's not as bad as it is on a 16" M4 but it's still not what I wanted.
    Still, a good upper if that's ok with you.

    Bcm socom upper reciever

    Posted by Billy on Jul 26th 2020

    After I received it I removed the front sight and delta ring. The front sight is a B$&@“ to get off. First taper pin was anyways the second towards reciever came out easy. the mil in the barrel was a little small And so the taper pin was in there pretty tight. I need a small heavy hammer but no no worries. Everything else is great. The finish is a little more basic than high priced rifles but everything is a nice tight fit and functions well.
