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.

Flawless September 22, 2016
Reviewer: Sean Tuitele from Charles town, WV United States  
Perfect uppers, my wife was depressed that your lowers were out of stock.

It's painful putting another brand lower on this upper.

Painful.

Thank you for what you do. We are grateful for your team.

A thing of Beauty September 22, 2016
Reviewer: Graciano Etrata from Stafford, VA United States  
I was doing a 300 Blackout pistol build and had my lower completed. In my research I came across the 9" upper. Fairly pricey but BCM has a good reputation. I posted a few questions before I made the purchase. All were returned within 24 hrs. I placed my order and waited for xmas. I was not disappointed. The upper receiver group was a thing of beauty. Professionally assembled, complete, and came with some swag. I took it to the range the next day and I was shooting tight groups in no time. I did have a follow on question to BCM about a white dot on my BCG and in true BCM fashion they were quick to respond with (that is how they mark that the BCG has been assembled with the special o-ring for a 300blk). Outstanding  customer service an Outstanding product,
