Action Closed

The cutaway section at the front of the metal receiver bridge across the rear of the action provides a guide for insertion of the loaded clip. As the bolt handle is turned up, its lower end where it faces the cylindrical bridge section of the receiver moves against the inclined plane to provide the leverage necessary to loosen the cartridge in the chamber and provide primary extraction. Thus as the handle is raised, its bearing against the plane (or cam) surface on the receiver bridge compels the unlocked bolt to pull back away from the face of the cartridge chamber.
