Gewehr 43

The Gewehr 43 or Karabiner 43 (abbreviated G43, K43, Gew 43, Kar 43) is a 7.92×57mm Mauser caliber semi-automatic rifle developed by Germany during World War II. The design was based on that of the earlier G41(W), but incorporated an improved short-stroke piston gas system similar to that of the Soviet Tokarev SVT-40. It was manufactured using innovative mass-production techniques.
