The MG42 (Maschinengewehr 42) is a German World War II-era open-bolt machine gun, chambered for the 7.92×57mm Mauser round. It supplanted the earlier MG34 in 1942 due to lower manufacturing cost thanks to dominant stamped metal parts. Its highest cyclic rate of fire at 1200 RPM, made the weapon gained the nickname Hitler's Buzzsaw.
