  • Patent number: 6032395
    Abstract: A pump action shotgun that has been designed to accept a shotgun shell magazine that can be quickly and easily attached or removed. An aperture is formed in the bottom surface of the receiver forwardly of a trigger housing assembly aperture. The top end of the magazine has a feed lip assembly that restricts the upward travel of the shotgun shells prior to their being transported to the rear end of the gun barrel by the bolt assembly as it travels forwardly. A spring loaded tang extends downwardly from the front bottom surface of the bolt assembly and travels through the feed lip assembly where it engages the rear end of the upper most shotgun shells and carries it forwardly to the rear end of the gun barrel. A bolt slide that is detachably secured to the bottom surface of the bolt assembly has a concave bottom surface that allows it to travel forwardly and rearwardly over the top of the feed lip assembly of the shotgun shell magazine.

  • Patent number: 5974718
    Abstract: A recoil system for the butt stock of a firearm having a recoil suppressor assembly whose front end is mounted in the cavity in the rear end of the butt stock. The piston ram of the recoil suppressor assembly in its static position extends rearwardly into a bore hole cavity of an elongated recoil housing. When the firearm is shot, the elongated body portion of the recoil suppressor assembly and its transversely extending mounting flange portion instantaneously travel rearwardly into the bore hole cavity with the bore hole of the body housing reciprocally traveling over the piston ram. An extension coil spring whose front end is secured to the front end of the body portion and whose rear end is secured to a cam assembly returns the elongated body portion to its static position once the recoil of the firearm has been suppressed.

  • Patent number: 5722195
    Abstract: A pistol grip recoil system for a shotgun or rifle and it has a pistol grip recoil assembly having a recoil base member and a pistol grip. The recoil base member is detachably secured to the rear end of the receiver of the firearm and it has an inverted T-shaped rail formed on its bottom wall. This inverted T-shaped rail is captured within and slides in an inverted T-shaped groove in the top end of the pistol grip. A recess formed in the front wall of the pistol grip adjacent its top end allows the trigger guard of the firearm to travel rearwardly with respect to the pistol grip when the firearm is fired. Various embodiments utilize springs to return the recoil base member forwardly to its static position after dissipating the recoil of the firearm resulting from its being fired.

  • Patent number: 5600083
    Abstract: A magazine filled with ammunition that can be quickly and easily attached to and detached from a firearm. It has a snail-shaped housing with a laterally offset chimney section that has an outlet port at its top end for feeding the ammunition into the firearm. The magazine is capable of being attached to the firearm at two 180 degree separated positions to accommodate a left or right handed person. There is an annular chamber in the housing of the magazine and it contains a spring-loaded drum. A pair of laterally spaced cog gears are mounted on the drum for capturing ammunition shells and transporting them along a circular axis until they reach the vertical linear axis of the chimney section. A follower assembly pushes the ammunition shells up through the chimney section. A shell retainer unit is mounted in the chimney section for preventing shells from exiting its outlet port when the magazine is detached from the firearm.

The shell retainer unit is deactivated by a depressor member that moves downwardly when the magazine is attached to the firearm. A feed lip assembly is pivotally mounted adjacent the top end of the chimney section.
