  • Patent number: 5375360
    Abstract: A recoil pad assembly (10) fitted to the stock of a weapon (W) such as a rifle or shotgun for cushioning a shooter (M) against recoil forces produced when the weapon is discharged. A first pad member (12) is installed on a butt end (E) of the stock (T) of the weapon. A second pad member (14) is pressed against a shoulder (S) of the shooter when the shooter prepares to discharge the weapon. The second pad member interfits with the first pad member for movement of the pad members relative to each other when the weapon is discharged. Compression springs (56) then restore the pad members to their original position relative to each other. A seal is effected between the pad members when the weapon is discharged trapping air between the members. Relative movement of the pad members then compresses the air producing a cushioning effect which lessens the recoil force to which the shooter is subjected.

  • Patent number: 5317825
    Abstract: A choke assembly (10) is attachable to the muzzle end of a shotgun barrel (G) to produce a tightened shot pattern when the shotgun is fired. A shotgun shell includes shot (S) and a wading (W). The wading is spun through the barrel by discharge gases created when the shell is fired, and this spinning motion tends to increase the size of the shot pattern. The choke comprises an elongate hollow tube (12) having an inner end (14) receivable in the muzzle end (M) of the barrel. An inner diameter (D1) of the tube corresponds to that of the barrel at its muzzle end. An outer end (24) of the tube extends beyond the muzzle. The inner diameter of the tube decreases from the inner to the outer end of the tube to effect a choke. The outer end of the tube also has a plurality of longitudinally extending slots (28) formed therein, these being spaced circumferentially about the tube. Discharge gases propelling the wading through the barrel tends to force the wading radially outwardly through the slots.
