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 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.
