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 carbine buffer with subsonic ammo and a H3 buffer with high velocity ammo. 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

    Awesome 300 Blackout Upper!

    Posted by Marc E. on Dec 27th 2016

    I have this 16" Upper matched with my Spikes Tactical Lower and the fit is amazing! I absolutely love the Keymod handguard and the compensator looks pretty damn cool! Great products from BCM as usual. Can't wait to take her out to the range!

    BCM 16" 300 BLK upper

    Posted by anonymous on Dec 27th 2016

    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%

    Posted by J Putney on Oct 13th 2016

    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.

    Awesome product. There are no downsides ever to using BCM products. I recommend them all the time to friends as I watch them go through rifles trying to beat the price or out do what you provide. I'll keep buying. This is my second rifle from you third upper from you guys. Thanks and keep it up.

    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.
