The G-3 Locking System is which mechanism?

Explanation:
The G-3 locking system is roller-delayed blowback. In this design, two rollers in the locking piece engage a curved cam surface in the receiver. When a round fires, the bolt tries to move back, but the rollers ride along the cam and provide a controlled delay before unlocking. This delay lets the chamber pressure drop to safe levels before the bolt can unlock and continue rearward. That roller-based mechanism is what distinguishes it, rather than levers, pawls, or ball bearings, which are not used in the G-3 locking system.
