The Sa-58 (vz. 58) is a 7.62mm assault rifle designed and manufactured in Czechoslovakia. The Sa-58 externally resembles the Soviet AK-47 but is internally a substantially different design based on a short-stroke gas piston, which shares absolutely no parts with the Kalashnikov design - including the magazines. The Sa-58 CCO is a variant of the Sa-58V that adds an Aimpoint sight for improved aiming ability as well as desert camo. In ArmA 2 it is only available with the ACR DLC.
