The Sa-58 (vz. 58) is a 7.62x39mm 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. In DayZ, however, AKM magazines may be used with this weapon.
This version the Sa-58V sports a folding para-trooper style stock, increasing mobility but decreasing the range to 200m.
