  • Patent number: 5438787
    Abstract: The gun storage and rapid removal mount of this invention is for securely retaining a shotgun or the like against unauthorized removal with the mount providing for rapid removal by authorized persons. It comprises a trigger guard cup and a forward lock clamp. The lock clamp engages the barrel and a magazine tube just forward of the shotgun receiver to prevent forward motion of the shotgun in the mount. The trigger guard cup prevents rearward motion. The lock clamp is both lock- and spring-retained. When its lock is released, the gun can be rotated out of the clamp against spring force. The spring also permits reinsertion of the shotgun into position against the spring force.
