These 14.5" mid length gas barreled upper receiver groups have been specifically tuned to be a very soft and fast shooting set up. They are a joy to shoot, but please feed it good ammo. With good milspec pressured ammo we have been running H buffers. We do not recommend using lower powered ammo. If using less than milspec pressured ammo, it may be best to run a standard carbine buffer.
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 Flat Top Receiver & Barrel Extension

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.

    Product and shipping great, but...

    I love my BCM uppers. This is my second one. Fit and finish areading perfect.

    I, fortunately, ordered and received, before July 20th.

    I deducted 1 star due to the fact that you folks at BCM have been scared by our, MA, attorney general. We can still receive parts for AR's. However, you folks won't even ship a sling to us anymore. Why is that? Nothing b illegal about it. If it was a lower or complete rifle, I understand. But we can still legally get parts.

    Thankfully there are other companies that will ship parts to us. So my 14.5in upper will be my last order from you folks. Even if you decide to send parts to MA.

    quality outweighs price

    Bought this for a build I did as a gift. Ended loving it so much, now I'm going to build one for myself using this upper. Fit, finish is great, and 500+ rounds through it for break in first time out had zero issues and consistent groupings.

    14.5" mid length URG with pinned flash suppressor

    Excellent quality, my BCM Upper Reciever Group is the perfect fit/finish for my new AR carbine, hands down. I'm very pleased with the looks and functionality, just what I was looking for!
    You can't go wrong with Bravo Company! Thanks

    Simply amazing!

    This upper is amazing. Shoots very soft and the 14.5 barrel has proven to be very controllable. Wasn't sure my BCM 16' midlength upper could be outdone, but I have a new favorite.

    Solid Upper

    I wanted a pinned/welded 14.5 with front sight, and this fit the bill nicely. The rails come way back on the top of the upper, unlike some others, so you an mount a scope farther back if you like. The bcg and bolt appear very high quality, and have a coating that feels slick, and hopefully will enable the carbon to be removed from the bolt more easily. The box included a hat and other swag, which is a nice detail. I made a mistake about an issue, and complained to customer service. They responded quickly, even though it was my mistake. I'm saving for a Bravo 20" DMR barrel now for that build.

    My third BCM upper. As with the others, this one is perfect. I bought this one for a rental rifle for my business. Couldn't be happier. Had the BCM comp mod 1 pinned and welded. Excellent job on that. Customer service is top notch. Plus I always get tons of stickers, reading material and a great BCM hat with an upper order. If you are on the fence about anything from BCM, buy it. You won't regret it.

    Awesome but one minor problem

    I recently picked this up to finish out a truck rifle build. The price is well worth it and the fit and finish top notch (like all other bcm products) but I do wish there were a round end cap instead of triangular. I also absolutely love the tons of swag that came with it, took me by surprise.
