Designed to launch 30 caliber bullets from AR-style platforms, the 300 AAC Blackout cartridge has become extremely popular among many types of shooters. This 220 Grain subsonic ammunition with Open-Tip Match (OTM) bullets shoots better than a 9mm MP5 in penetration and accuracy. The brass features a standard 5.56mm taper which minimizes strain on the bolt's weaknesses.
