The CETME/G3 uses the delayed roller blowback system which was spawned by German engineers right at the end of WW2. It was destined to potentially be the successor to the StG44, and a few prototypes were made, but it never got into production. The same German engineers landed up in Spain post war and their efforts manifested into the CETME - a 308 delayed roller blowback battle rifle. Ultimately Germany adopted the exact same rifle with minor modifications in the guise of the G3.
