System and method for loading and feeding a shotgun

Abstract

A trigger group assembly for a semi-automatic shotgun includes a follower pin that is slideably attached to a sliding track assembly. The follower pin engages a pair of tracks to facilitate cooperation the sliding track assembly's carrier with the shell retainer of a detachable magazine in such a way that when the bolt is propelled rearward, a cartridge is released from the magazine, and when the bolt is propelled forward, the cartridge is lifted by the carrier into the path of the bolt and loaded into the chamber of the firearm.

AI Technical Summary

Benefits of technology

[0008]In a further aspect of the present invention, a trigger group assembly is operatively coupled to a bolt and a carrier of the semi-automatic shotgun, wherein cartridges are loaded from a high-capacity magazine and fed into a firing position. The trigger group assembly comprises a track assembly including a feeding track and a loading track—each track having a first terminus and a second terminus. A pair of deflectors—a first and second—each extend from the track assembly proximate its opposing ends. A spool is operatively coupled to the track assembly, wherein during movement of the track assembly, the first and second deflectors facilitate transition of the spool between the feeding and loading tracks.

[0012]Another object of the present invention is to provide a semi-automatic shotgun having reduced recoil.

Problems solved by technology

Although the shotgun has been proven effective as an entry weapon wherein close-quarters impairs the use of long-barreled and / or high-powered weapons, its limited ammunition capacity, lack of interchangeability among ammunition types, and relative lengthy reloading time renders today's shotgun less than adequate in an urban-combat arena.

Unfortunately, today's sporting shotguns adapted for law enforcement and military purposes provide an unsatisfactory option for many tactical situations.
