KAC PN 31970

The SR-30 takes advantage of the .300BLK, offering a 9.5” barrel that is as capable as an 11.5” 5.56mm SBR, for a significantly more transportable and maneuverable firearm. The QDC compatible Flash Hider will mount any of the KAC 7.62mm QDC suppressors. The SR-30 has 99% parts compatibility with the SR-15, requiring only a dedicated barrel and muzzle device. Seamlessly transition from subsonic ammunition to supersonic with nothing more than a change of the magazine.
