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.

    Fantastic Product! Ran flawlessly! A+

    First time building a 300 Blackout. Used BCM's stock trigger group combined with upper receiver group. Using Sig Sauer Subsonic, Supersonic and Hornady Subsonic ammo. It ran flawlessly with zero issues! I love the product quality and set up! Awesome company communication with quick responses. A+

    Flawless

    I ordered the 9" Blackout upper and 16" Blackout upper in the same week. Received both within 3 days and I can't say enough about the quality. Flawless fit and finish. Exceeded my expectations. Even nicer than my high end rifles. Both have been ran several hundred rounds at the range suppressed and unsupressed without a single hiccup.

    Great Condition

    It arrived in great condition and mated with no issues to a Aero Precision Pistol Lower with a BCM lower parts kit. Everything seems good at this time. But due to weather and work I have not had the chance to take it to the range yet. But it looks like it is going to be a winner.
