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 1/8 Twist Rate
The USGI 1/8 twist rate of all BCM Stainless barrels is the preferred twist rate by the DoD and 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 SS410 Barrel Steel
this 18" 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.

amazing! November 2, 2015
Reviewer: William Matsuda from Issaquah, WA United States  
The shipping was really fast, My upper came to the door in exactly a week from my order date! Upon receiving the package I assembled it with my arrow precision lower, and it look awesome! the rifle is light, not too long, and has a very corrosion resistant stainless steel barrel on it. I cant wait to take this upper to the range!

Excelent combination of light weight and accuracy November 2, 2015
Reviewer: Anonymous Person from GA, United States  
Wanted a upper that was accurate enough to be fun AND light enough to be handy and this upper delivers.

Very impressed with the KMR hand guard which is stupid light. The lockup system will not loosen over time like i have experienced with some free float rails I've used in the past.

Barrel appears to be accurate and shoots about 1.5ish inch 5 shot groups at 100yrds with most ball ammo I've tried and shoots under an inch with prvi 69 grain match which is mostly what it gets fed when i'm not shooting regular ball. It's been flawless reliability wise (although i doubt its ever been though more than a few hundred rounds without a cleaning). I don't doubt it might shoot slightly better with more expensive ammo but I am very satisfied with the upper's accuracy. My only quibble is the high shine finish of the barrel. Several people I've shown the gun to seem to like it but i would prefer a dull stainless finish.

Couldn't be happier July 18, 2014
Reviewer: Anonymous Person from Silicon Valley, CA United States  
I spent a lot of time researching what I wanted for my first AR. After much research, I settled on a BCM SS410. Getting it with the KMR was a no brainer.

The result is a very well balanced rifle with a VLTOR iMod Clubfoot stock. It's very light considering the match stainless barrel due to the incredibly light KMR.

This thing is also very accurate. When I do my part, I can get around 1/2 MOA shooting off an Atlas bipod with a rear sand bag with a 3-12 scope.

Even though it's a precision build, the light weight and good balance make for great handling when shooting offhand with irons at shorter ranges.

I know people are excited about the new lightweight barrels by BCM, but don't discount the option of a good Recce Precision build with this excellent upper.
