The G-3 locking system is which type?

• A. Lever
• B. Pawl
• C. Rollers
• D. Bolt

Answer: (C)

The G-3 locking system is a roller-delayed blowback arrangement. In this design, two small rollers in the bolt head lock into recesses in the receiver. When a round fires, the pressure pushes the bolt back, but the rollers must ride up cam surfaces and clear the locking recesses before the bolt can unlock. That brief delay lets the chamber pressure drop to a safe level before extraction begins, controlling the impulse and preventing a slam of the bolt. This rolling, cam-driven delay is the hallmark of the roller-delayed type, unlike lever- or pawl-delayed systems or a simple bolt-only arrangement.
