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: 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.
 

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 commercially available precision barrels.
 
 
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.
 
 
5.56 NATO Match Chamber (USMC SAM-R Chamber)
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.  The SAM-R chamber is the precision version of the 556 NATO chamber.

    My first AR

    Posted by Doc Steelegrave on Dec 28th 2016

    I am new to the AR platform but not customer service as my wife and I own a manufacturing business. My emails with all kinds of questions were always answered within an hour or less of being sent. Wow! Great company, great product and did I mention all the swag that was included with my order👍👍
    You cannot go wrong with Bravo Company!

    Great upper

    Posted by JC S on Dec 27th 2016

    this was my first BCM product and it did not disappoint. The quality is top notch and the barrel is very accurate even with fmj bulk ammo 55 gr. The muzzle device works really well. I will be buying BCM from now on. The price is worth it.

    Love it!

    This is my first BCM product and it's living up to the hype. Only about 200 rounds through it, but so far I'm very pleased with it. I put it on a Palmetto State lower and it fit like a glove. On top of that, I ordered it on a Friday and I got it on Wednesday. Very happy I went with BCM.

    BCM SS410 Mid URG w/KMR-A15

    Posted by Robert Sumner on Sep 22nd 2016

    Simply the best KeyMod rail option available. Rating 4 stars due solely due to the shiny stainless barrel that should be bead blasted as a standard to tone it down.

    BCM SS410 16" Mid Length Upper Receiver Group w/ B

    Posted by Roberto Herdocia on Jun 19th 2016

    This is my second one, and it is the best upper I have ever had, and I own many from Noveske to Armalite, to Colts and Daniel Defense. By far the most accurate barrel I have ever shot in an AR 15. Top quality. I am hooked to the BCM uppers. I will eventually swicth all my uppers to this BCM SS410 16". Upper receiver is also well made.

    Great Upper!

    Posted by Brandon on Jun 13th 2016

    This is my second upper from BCM my first 16inch full length hand guard. Very impressed with the quality and equally impressed with the fast two day delivery. I have it mounted to their BCM lower with BCM lower parts kit. No play between the upper and lower. Fits well and light weight! I highly suggest BCM! I haven't shot the gun yet still in the process of finalizing irons and optics right now but plan on enjoying this rifle for many years and hopefully use it for two gun once I get some trigger time!
