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.
 
These upper groups come installed with the Midwest Industries SS(Gen 2)-15" Handguard, barrel dimpled for strong install of Low Profile Gas Block.
 

 

BCM® SS410 Barrels
This BCM® stripped barrel is machined from a 410 stainless steel. It features hand lapped button rifling with a 1/8 twist rate and M4 feedramps. To give the shooter the best balance of weight and accuracy this BCM® barrel has a mid-weight profile and a rifle length gas system.
(410 stainless is a harder and more corrosion resistant than the conventional 416 stainless found in most barrels.)

 

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.

    Bravo Company strikes again!

    Posted by T on Nov 11th 2015

    This is my 3rd BCM upper, and they've gone 3 for 3 on all fronts. I spent 30 minutes nitpicking over it once I received it, and could find nothing except perfection. Thanks for the great upper guys!

    18" upper with MI ssk-15 handguard

    Posted by Mario Mitchell on Nov 11th 2015

    It was a pleasure to do business with Bravo Co. They had what I was looking for in stock and shipped it out right away. I have not got to use the new upper much yet but like it thus far. Can't wait to get more trigger time in with it. I will be using Bravo Co. in the future for my AR-15 needs.

    Upper arrived in 4 days, well packed. Took it to the farm the next day to sight in shoot some targets, impressed with accuracy. Accuracy of this upper is beyond what I had expected.
