BCM® has taken great care to ensure the best possible performance and interchangeability. However, due to the large operational range of 300 Blackout ammunition in the market place, BCM® cannot guarantee function will all ammunition types in all conditions. These barrels were designed to run with a H3 buffer with high velocity ammo.

If running subsonic ammunition, it is recommended to run your suppressor and a carbine buffer. Fine tuning may be required in limited instances based on ammo and buffer choices that work best for the desired application. BCM® also recommends running the Crane O-ring (provided with all BCM® Bolt Carrier Groups) over the extractor with 300 Blackout.

    .300 complete upper

    The workmanship and finish on this upper was flawless. I assembled on to a RRA lower and it fit very tight with zero movement. I've only run about sixty rounds of subsonic through it but it ran perfect and all casings landed in one small pile about six feet away at 3:30 Packaging and shipping was very good. I'm very happy with this and would purchase again.

    Great

    Running this with a kak shockwave brace and buffer tube combo and the Bcm bcg, it ran fine with super and subs and is really lightweight

    Exceeded my expectations

    Very fast shipping and excellent customer service. I had submitted a question to BCM prior to making my purchase, and they were very quick to reply with detailed information addressing my concerns. The fit and finish of this upper is superb. My tax stamp is still pending, so I have yet to shoot it, but I can only imagine it shoots as well as it looks!

    Quality delivered fast

    Bravo made quick deliver on a quality product. Couldn't build it for less. Key mod hand guard has a good feel in my hand instead if a strait railed setup. Carbine buffer will cycle super and subsonic ammo. I added the bcm bolt group since it is offered at an incredible value if you buy the upper.
