ABSTRACT:
A secondary recoil absorption mechanism absorbs some of the recoil energy associated with the firing of the firearm. The secondary recoil absorption mechanism includes a roller mounted on the breech block to engage a ramp element pivotally mounted on the frame of the firearm. The ramp element includes a rounded corner against which the roller abuts. The ramp element is connected to a cocking lever by a roller mounted in a guide groove defined on a cocking lever. The cocking lever is moved manually to move the ramp rounded corner out of the path of movement of the breech block mounted roller and to move the breech block into a cocked position held behind a sear. The guide groove includes a plurality of sections.
