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.
Mil-Spec SS410 Barrel Steel
this 16" BCM barrel is machined from SS410 stainless steel. Featuring hand lapped 1/8 twist rate button rifling and M4 feed ramps barrel extensions, the 410 stainless barrel gives the shooter the best balance of weight and accuracy. 410 stainless is also harder and more corrosion resistant than conventional 416 stainless found in other precision barrels
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.
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.

You get what you pay for September 22, 2016
Reviewer: Chris from Altamont, NY United States  
I purchased this upper as a complete assembly less charging handle. This is my first BCM, but not my first ''top tier'' build. The materials and finish are of excellent quality, and considering it's a stainless barrel, it's very light.

More importantly, it's very accurate. I have only taken it to the range once so far to break in the barrel, and it was depositing XM193 into a 1.25 inch group at 100 yards using Nightforce glass. At this point, I'm very interested to see what it will do with match grade ammunition seeing as how it's already near MOA with milsurp ammo from the 90's.

BCM of course shipped the upper well packaged and with several BCM goodies. Shipping time was quick, too. Thanks for the deal, guys!

Bravo truly makes some of the best products dollar for dollar without exception. Having been in this field for many years it's truly amazing what you get for the cost.  I have ordered many different products and gear from Bravo and I am always pleased with the fit, finish and function of every part I've ever ordered. Their quality is exceptional, customer service is superior and accuracy exceptional, because of this I continue to return to Bravo for all my tactical needs!

Outstanding Upper! September 22, 2016
Reviewer: Dave from Prattville, AL United States  
This upper receiver group lives up to the hype.  Very accurate with my 55, 62, and 75 grain ammunition, producing 10-shot groups under 2 inches at 100 yards with all three loads, and the first 5 62 grain rounds went into a ragged hole 0.5 inches across.  Buy with confidence.

Glad I went with Stainless Ion/KMR Alpha April 27, 2016
Reviewer: Nichols from BIRMINGHAM, AL United States  
Very nice barrel, shooting under two inch groups at 100 yds. using a red dot first time out to the range. The receiver group functions flawlessly and the KMR Alpha is very light weight. I'm 100% satisfied. BCM has been great to deal with from customer service to super fast shipping, a top notch company.
