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 Condition December 28, 2016
Reviewer: Jeff from Pierre, SD United States  
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.

Super light December 28, 2016
Reviewer: Frank Petrini from Austin, TX United States  
I've been building ARs for years. I decided to build an ultra lightweight SBR, and found I couldn't build it any cheaper or with better parts than buying this upper complete. I'm super happy with this, and the 11.5" 5.56 upper I bought to interchange on my SBR lower.
Highly recommend
