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.

    Fast shipping/Awsome Upper

    I ordered a 12.5 300 blk upper for a hunting rig I was putting together and to my suprise BCM had it to my door step in 4 days. I’m so use to getting stuff from amazon in lighting speed and didn’t expect this upper to arrive so fast. Slapped it on my lower put the scope on and went to sight it in. This upper runs flawlessly and will touch holes at 100 yards. I am very happy with the accuracy that this barrel provides and with Barnes 110 blackeys my son was able to get his first buck this season with it. Thanks Bravo Company for outstanding shipping and a fanstatic product, I will be a repeat customer!
