The CETME Model 58 is a stamped-steel, select-fire battle rifle produced by the Spanish armaments manufacturer Centro de Estudios Técnicos de Materiales Especiales (CETME). The Model 58 used a 20-round box magazine and was chambered for the 7.62×51mm NATO round (although originally designed for the 7.92×41mm CETME cartridge and later for the reduced power Spanish 7.62×51mm cartridge). The CETME 58 would become the foundation of the widely deployed German Heckler & Koch G3 battle rifle. Semi-automatic variants were also produced for the civilian market.
