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.

    BCM 16" 300 BLK upper

    Having put the BCM 300 BLK upper on the Stag lower taken from my 3-gun rifle, I've taken it to the range three times. Shooting 220 grain SMK unsuppressed I was struck by this, that BCM sized the gas port just right to work with the more common buffer/spring combinations. The barrel has proven accurate. It's relatively light and maneuverable.

    I Roll 5.56 - 90%

    I like what Frank Proctor has to say about 5.56 at 600 meters. Shooting 300 blk has its pluses and minuses and will depend on your application. Subsonic - cqb - rock that. And, that's why I have this instrument at my ready.
    BCM complete uppers are factory tested and a lot of value to your total build equation. This particular instrument is not paired with and BCM lower. In this case I have a Battle Arms - forged gen 1 lower with multiple parts from many suppliers.
    Outside of the trigger(which is totally preference based by application and will remain nameless other than to say it was not a part of a standard milspec lower parts kit) - the alpha KMR & BCM barrel, ambi charging handle and BCG on this gun makes it an excellent selection. In fact three of the last AR builds have been 100% BCM.
    Great quality gear - if you need to get down.

    Another excellent purchase and experience

    This was my second purchase from BCM - the website is/was flawless, the transaction was a breeze, and my 300 AAC upper arrived faster than I expected. I regret only giving a five star rating because there's not an opportunity for a 10. Thank you BCM for this excellent experience. I will be back.

    Perfection

    The upper is flawless. It mounts to the lower I already had with zero play. Like none. The rifle feels amazingly solid. Works as advertised, just boring reliability. No funny "it stovepiped" stories for me I guess. These things just run.

    Smooth upper

    Shoots like a dream and looks great. Lightweight and functional. Mates perfectly with my lower. Good stuff.
