Knights Armament SR-30

The SR-30 E3 Mod 2 takes advantage of the .300 BLK, offering a 9.5″ barrel that is as capable as an 11.5″ 5.56 mm SBR, for a significantly more transportable and maneuverable firearm. The QDC compatible Flash Hider will mount any of the KAC 7.62 mm 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.
