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.

Icing on the cake of my first 80% lower AR pistol October 27, 2017
Reviewer: Texas from Tacoma, WA United States  
AMT 80% lower, JP enterprises gen 2 silent buffer spring, ALG defense ACTrigger, 5DTactical jig, surefire mini can over surefire compensator.  Tight groups 50,100, and 200 with sub and supersonic without waking up the neighbors.  BCM is the standout on fit and finish.  Thanks for the excellence.

Great Experience October 27, 2017
Reviewer: James Carmon from Kennesaw, GA United States  
Prompt service (the credit card / shipping requirements suck) and Bravo Company threw in lots of free swag!  I will certainly purchase again from Bravo Company!

Too bad the BATF does not move as quickly, as I will not be able to use the upper for probably 6 mos.

300 Blackout Complete Upper October 27, 2017
Reviewer: Christopher Griffin from Richfield, NC United States  
Terrific quality and quick shipping with BCM swag.   This is why BCM uppers have homes on 3 of my rifles so far.  Terrific company.

Solid company October 27, 2017
Reviewer: FRANK CARUSO from Gilead , ME United States  
I've been wanting a BCM upper for a while after many word of mouth recommendations. Just waiting on my stock for my build to be complete, so I haven't run it yet. Fit and finish are excellent! Had to take off that beautiful comp mod 1(no A2 birdcage here!) to fit my can, but I'll use it somewhere!  Slim handguards even with rail covers installed. And thanks guys for all the BCM swag! It was like Christmas all over again. Semper Fi brothers.

9" 300BLK October 27, 2017
Reviewer: Jared Dana from Pardeeville, WI United States  
This is nothing short of amazing! Haven't found anything yet that shoots larger than an inch out of it. If you're hesitating about getting one; stop and add it to your cart!
