The CETME C2 (also named the CB-64,) is a Spanish submachine gun based on the British Sterling L2A3. It is an open-bolt, blowback-operated firearm that fires the 9×23mm Largo and 9×19mm Parabellum pistol cartridge. Designed in the 1960s, the C2 has many notable safety features built into it and was later used to replace the Star Model Z-45 submachine gun series for Spain in the 1960s however, was later superseded by the MP5 and Star Z-84.
