Abstract
A device for reducing firearm recoil comprises a case having an elongated interior chamber therein, a piston received in the chamber, a plurality of vanes extending from the piston surface, and a liquid substantially filling the chamber. The piston is supported between front and rear return springs. The device is inserted in a gunstock, and recoil energy of the firearm, when fired, is dampened or slowed as the case and liquid are driven rearwardly against the resistance of the piston.
Claims17
A firearm recoil reducing device comprising
- a case enclosing an elongated interior chamber,
- a piston received in said chamber having a plurality of vanes along the exterior surface thereof and supported between a front and a rear spring, and
- a liquid substantially filling said chamber.
A device for damping firearm recoil comprising:
- a case having a chamber therein,
- a liquid substantially filling said chamber,
- a piston spaced apart from chamber walls and moveably received in said chamber having one or more members extending outwardly from a piston surface for resisting piston movement in said liquid, and biasing means for returning said piston to a rest position after firearm recoil.
