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.

Great accuracy May 8, 2019
Reviewer: Hale Yeah from TX United States  
I didn't buy this upper to shoot 100 yard groups but when I did I was very surprised at the results! It shot consistent 3/4 inch groups at 100 yards with quality hunting ammo and about 1 1/4  with bulk ammo.

Like all BCM products, this is a high quality upper and worth every penny!

Excellent so far April 10, 2019
Reviewer: Stoneythekid  
I already own Colt and Daniel Defense rifles, after much research and recommendations decided to give BCM a try. Excellent performance so far (only a couple hundred rounds). It is lighter than I expected, finish and assembly is flawless, very fast shipping and excellent customer service I will definitely buy from BCM again and would recommend them to anyone considering.
