Patent ID: 8413361

Claim:
A firearm comprising: a frame; a barrel; a stock including a body; a recoil pad; and a hydraulic kick absorption mechanism connecting the recoil pad to the body such that a space is defined between an end wall of the stock and an end wall of the recoil pad adjacent the hydraulic kick absorption mechanism, the hydraulic kick absorption mechanism including a return spring pushing the recoil pad away from the body of the stock when the hydraulic kick absorption mechanism is in a rest position, and enabling the space between the stock and the recoil pad to decrease during discharge of the firearm, the hydraulic kick absorption mechanism further including a shock absorber comprising: a cylinder connected to one of the recoil pad and the body of the stock; a piston mounted in a sliding manner within the cylinder; a rod integrally connected to the piston and partially extending from the shock absorber, wherein the rod is also connected to one of the body of the stock and the recoil pad; and first and second oil chambers within the cylinder, the first and second oil chambers being connected via a first calibrated oil passage such that a volume of oil within the first oil chamber decreases under the effect of the piston while a volume of oil in the second chamber increases; and wherein the shock absorber is positioned within the stock and the stock is positioned with respect to the recoil pad such that, when the recoil pad is positioned against a shoulder of a gunman and a cheek of the gunman is positioned against the stock in a shooting position, and the firearm is discharged by the gunman, the body of the stock has a tendency to move downward with respect to the recoil pad and the shoulder and the cheek of the gunman.
