Radialblock Verschlüsse – Radial breech block

The breech is a quadrant block which houses the concealed hammer. When the loading hammer is actuated, the radial block rotates 90° into the housing hereby exposing the chamber, ejecting any cartridge cases and cocking the hammer at the same time. (examples: Schulhoff, Widmer) When the radial hammer helps to lock the radial breech it is called a Rolling Block system (example: Remington).
