How Does It Work: Roller Locking
This video from Forgotten Weapons explains the roller locking mechanism, differentiating it from roller-delayed blowback. It highlights that roller locking is a sub-type of flapper locking and is notably used in the MG42 and the Czech vz.52 pistol. The system utilizes rollers to secure the bolt and barrel during firing, relying on an external mechanism like short recoil for unlocking and cycling.
