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: 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 20" 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.

5 of 5 Bravo co. Is the only way to go! April 10, 2019
Reviewer: AJ Russell from Liverpool , NY United States  
I have purchased 7 complete upper receivers, many lower parts kits and stock assemblies,  in addition to several other odds and ends from BCM. Not only are the products always top notch compared to any other company I've purchased from, but every order is delivered extremely fast and without issue. One upper receiver I purchased had a loose low profile gas block which BCM promptly sent out a return label for. No questions asked. They treat every purchase as a top priority and I can honestly say I will never purchase my AR15 parts or rifles anywhere else but Bravo Co. Thank you all for upholding a very high standard in a world gone to mass production garbage! Many more purchases to come.

5 of 5 Less than .5" groups April 10, 2019
Reviewer: Matt from Orange, CA United States  
I ordered this upper a while ago. Should have reviewed earlier but I started reloading recently and with my 77gr noslers I am getting some tiny groups. Best one the other day measured .48" @100 yds with a 3.5# trigger. Only problem is I wear the hat they sent with it so much it looks pretty sad at this point.

5 of 5 Superb Upper! October 27, 2017
Reviewer: Chris from Orlando Area from Central Florida  
Granted, I'm not an expert by any stretch of the imagination but I purchased this upper receiver group to marry it with a lower that my Son & I put together and we could not be more pleased.  It has functioned flawlessly for the first several hundred rounds.  My only comment is that the one I clicked on and put in the cart was the stainless steel barrel without the Ion bond finish - but when the package arrived - the barrel with the ion bond was with my upper receiver & handgaurd - I shouldn't really complain as this was a more expensive option.

5 of 5 Excellent for a DMR December 28, 2016
Reviewer: Albert Ortiz from Long Beach, CA United States  
As always BCM quality is hard to beat at any price. I bought this 20" upper as a precision build. I received it very quickly with no issues. Looking forward to seeing how well it does on the range.
