The G3 rifle is a select-fire, magazine-fed, roller-delayed blowback rifle, developed by German engineers at Mauser Werke late in the 2nd World War and refined in Spain, at the CETME company.
Initial models of the G3 rifle were quite similar to CETME rifles, and even had "CETME" markings on the receivers (until 1961 or so). It is built around Vorgrimlers' roller delayed blowback system. This system employs a two-part bolt with two rollers. The front bolt part (bolt head) is relatively light and has a bolt face with extractor on it. It also has a hollow cavity at the rear, in which an inclined forward end of the rear part of the bolt is inserted. The system features two rollers, inserted from the sides into the bolt head and rested on the inclined forward end of the bolt rear.
