The G3 (Gewehr 3) is a 7.62x51mm NATO select-fire battle rifle developed in the 1950s by German armament manufacturer Heckler & Koch (H&K), collaborating with Spanish state-owned design agency CETME (Centro de Estudios Técnicos de Materiales Especiales). The G3A3 is a selective-fire automatic weapon that uses a roller-delayed blowback operating system. The two-piece bolt assembly consists of a breech and bolt carrier. Sliding cylindrical rollers hold the bolt in battery by engaging locking recesses in the barrel extension. When both rollers are compressed inward against camming surfaces driven by expanding gases, the breech opens. As rollers move inward, recoil energy is transferred to the locking piece and bolt carrier, which begin to withdraw while the bolt head slowly moves rearward with the bolt carrier. Once the bolt carrier clears the rollers, pressure in the bore drops, and the bolt head is caught by the bolt carrier, continuing the operating cycle. The bolt features an anti-bounce mechanism that prevents the bolt from bouncing off the barrel's breech surface. The bolt head locking lever is a spring-loaded claw mounted on the bolt carrier, grabbing the bolt head as the bolt carrier group goes into battery. The lever essentially ratchets into place with friction, providing enough resistance to be reopened that the bolt carrier doesn't rebound. A spring-powered claw extractor is also contained inside the bolt, while the lever ejector is located inside the trigger housing (actuated by the recoiling bolt).
