Designed to launch 30 caliber bullets from AR-style platforms, the 300 AAC Blackout (300 BLK) subsonic rifle ammunition with Open-Tip Match (OTM) bullets shoot better than a 9mm MP5 round in penetration and accuracy. The brass features a standard 5.56mm taper which minimizes strain on the bolt's weaknesses.
