Recoil suppression system for the stock of a firearm

1. A recoil suppression system comprising:

a recoil absorption assembly having an elongated body portion with a forward end and a rearward end with a generally flat mounting plate having an outer periphery, the mounting plate disposed transversely to the elongated body portion at the rearward end thereof, the elongated body having a cavity formed therein, the cavity being open at the rearward end of the elongated body portion, the mounting plate having a rearward projecting flange located within the outer periphery of the mounting plate, the recoil absorption assembly being received in a cavity formed within a firearm stock when the mounting plate is mounted on a rear end of the firearm stock;

a recoil housing having a rearward end, a forward end, and having a recoil plate at the rearward end with a forward projecting flange having an outer periphery, the forward projecting flange being at a periphery of the recoil plate, the recoil plate and forward projecting flange forming a cavity closed at the rearward end of the recoil housing and shaped similarly to the mounting plate and its rearward projecting flange, a piston ram member projecting forwardly from and being normal to the recoil plate, the piston ram member being receivable in the cavity of the elongated body portion and slidingly attached to the recoil absorption assembly for reciprocal movement in the cavity, the rearward projecting flange being received in the recoil housing cavity when the piston ram is attached to the recoil absorption assembly; and

a recoil reduction means configured to oppose the movement of the piston ram into the cavity of the elongated body,

wherein the recoil suppression system is configured to be received by the stock of a firearm, and

wherein at least a portion of the outer periphery of the mounting plate is larger than the outer periphery of the forward projecting flange.

2. The recoil suppression system of claim 1 , wherein the recoil reduction means comprises a coil spring having a front end and a rear end, the front end of the coil spring being detachably secured to the front end of the elongated body portion, a cam assembly having a rear lever arm that is pivotally secured to an end of a front lever arm, the rear end of the coil spring being secured to the front lever arm, the piston ram member having a cavity formed in a side wall that receives a roller cam mounted on an end of the rear lever arm.

3. The recoil suppression system of claim 1 , wherein the recoil reduction means comprises a torsion spring having a free end and an attached end, with the attached end of the torsion spring contacting at least a portion of a cam which is pivotally mounted to the rear end of the elongated body portion, the piston ram member including a cavity formed in a side wall that receives a portion of the cam, wherein the torsion spring opposes movement by the cam in at least one direction.

4. The recoil suppression system of claim 3 , wherein the torsion spring is attached to a first end of the cam and a roller cam is mounted to a second end of the cam, the roller cam being received in the cavity of the piston ram member.

5. The recoil suppression system of claim 3 further comprising a threaded stud inserted through a threaded bore hole formed in the mounting plate, wherein the free end of the torsion spring abuts an end of the threaded stud, a preload force in the torsion spring being adjustable by the rotation of the threaded stud.

6. The recoil suppression system of claim 3 , wherein the torsion spring and cam are configured to pivot about the same axis.

7. The recoil suppression system of claim 3 , wherein the cam includes a profile adapted to mate with a portion of the torsion spring.

8. The recoil suppression system of claim 1 wherein the elongated body portion, the mounting plate, and the rearward projecting flange are integrally formed as a single component.

9. The recoil suppression system of claim 1 wherein the recoil plate, the forward projecting flange, and the piston ram member are integrally formed as a single component.
