CETME (Centro de Estudios Tecnicos de Materiales Especiales)

The CETME Modelo C is a select-fire battle rifle developed by the Spanish state-owned CETME company. It was adopted by the Spanish Armed Forces in the 1960s as their standard service rifle. The Modelo C uses a delayed blowback roller-locked action similar to the German StG 45(M) prototype. It is chambered in 7.62x51mm NATO and features a wooden stock and handguard. The rifle is the direct predecessor to the Heckler and Koch G3 battle rifle.
