The CETME Model 58 is a Spanish battle rifle which was designed in mid 1950s, produced by the state-owned Centro de Estudios Técnicos de Materiales Especiales (CETME). Chambered for 7.62×51mm NATO and utilizes standard 20-round magazine, its design consists of stamped metal receiver and roller-delayed blowback mechanism.
It became the basis of the more well-known G3, while both weapons are visually similar, especially to the early G3 models with a wooden buttstock and a handguard with large perforations (post #3845109 for example).
