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 in every way

    This upper is truly a dream to shoot. Not only was it 100% reliable, but the carbine gas system made subsonic 300AAC rounds feel like .22LR. It didn't lock the bolt back after the last shot with the Remington UMC subsonics, but it still fed every round reliably. Fit and finish are top notch: exactly what I have come to expect from BCM.
