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.

    Assembly is first rate

    Used on a pistol lower. Attention to detail on assembly was excellent. Handguard top rail was aligned perfectly with the upper receiver rail. Gas tube is perfectly aligned with the bolt carrier key - no drag at all. This was purchased with the BCG and GF charging handle. Bravo Company's recommendations for buffer weight and spring are right on. 100% reliability on first test firing.

    Solid Purchase

    Had my eye on this for a while and knowing BCM's reputation for reliable-well made products I made the leap and I am so glad that I did. The 300 blk upper exceeded my expectations. Simply put...this is an exceptional product from a great company and from my history of using BCM products I can confidently and enthusiastically endorse this product. Plus I got lots of free swag such as a baseball cap, calendar, poster, and decals. If you are on the fence about a BCM product I urge you to give them a chance, they do not disappoint.

    BCM is the best

    Beautiful upper, Love the BCM logo everywhere and the 300 blackout above the ejection port, after all when you’ve got a bcm, you want people to know! They also loaded the box up will all sorts of goodies, stickers, gunfighter calendar, gunfighter magazine (for reading, good articles too) will definitely be building more BCM’s

    Great, quality upper

    Got this to complete a pistol build on a stripped lower. Fit to the Spike's lower is great, no wiggle at all. BCG is good quality, cycle is nice and smooth. Upper will cycle both supersonic and subsonic without a suppressor, which is a huge plus!
