The bolt and slide are positioned to align with the center of the barrel opening and to engage a removable box-style shotgun shell magazine. The assembly further includes a plurality of connectors to secure the assembly to the stock barrel, grip, trigger assembly, and magazine tube of the conventional shotgun. ## Claims ### Claim 1 A shotgun magazine receiver assembly for converting a conventional shotgun having a trigger assembly and barrel into a magazine loaded shotgun, said receiver assembly comprising: an elongated receiver body having a front end, a back end, a top surface, a bottom surface, and a pair of opposing side surfaces defining an interior space, each of the opposing side surfaces including an elongated channel disposed along an inside portion thereof, and arranged in a generally parallel orientation to each other; at least one connector disposed along the receiver body, said at least one connector having a location that is suitable for mating with a complementary connector disposed on the conventional shotgun; a shotgun barrel opening disposed along the first end of the receiver body; a trigger assembly opening disposed along the bottom side of the receiver body, each of the shotgun barrel opening, and trigger assembly opening including a dimension suitable for receiving a conventional shotgun barrel, and trigger assembly, respectively; a magazine opening disposed along the bottom side of the receiver body at a location adjacent to the front end of the receiver body, said magazine opening being configured to receive a removable shotgun shell magazine; a bolt having a font end, a rear end, a top surface, a bottom surface and a pair of side walls defining a firing pin chamber; a firing pin disposed within the chamber; a lock stop opening extending from the top surface of the bolt to the bottom surface of the bolt; an extractor arm recess located along each side wall of the bolt and adjacent to the front wall; and a spring groove disposed along one of the side walls of the bolt, each of the extractor arm recesses and spring groove being configured to communicate with a conventional shotgun extractor arm and spring, respectively. ### Claim 2 (depends on 1) The shotgun magazine receiver assembly of claim 1, further comprising: a shell ramp having an angled surface, said shell ramp being interposed between the barrel opening and the removable magazine opening along the front end of the receiver main body within the interior space, said shell ramp being configured to direct a shotgun shell from an inserted removable magazine into the shotgun barrel. ### Claim 3 (canceled) ### Claim 4 (depends on 1) The shotgun magazine receiver assembly of claim 1, further comprising: a slide having a front wall, a rear wall, a generally flat top surface and a pair of opposing side surfaces; an indentation disposed along the rear wall, said indentation being configured to communicate with the conventional shotgun trigger assembly; a pair of elongated slide guides disposed on the side surfaces, each of the guides being configured to slide within the elongated channels of the receiver main body; a lock stop disposed along the top surface of the slide, said lock stop being configured to be positioned within the lock stop opening of the bolt; and a pair of elongated fingers configured to engage an inserted removable shotgun magazine, and to remove a shotgun shell therefrom. ### Claim 5 (depends on 4) The shotgun magazine receiver assembly of claim 4, wherein the bolt and slide are removably secured within the main receiver body so as to align the firing pin longitudinally with a center of the barrel opening, and the slide is positioned above the removable magazine opening. ### Claim 6 (depends on 5) The shotgun magazine receiver assembly of claim 5, wherein the bolt and slide are configured to engage the conventional trigger assembly, and an inserted removable shotgun magazine. ### Claim 7 (depends on 1) The shotgun magazine receiver assembly of claim 1, further comprising: a spring actuated lever disposed along the bottom side of the receiver body at a location between the trigger assembly opening, and the removable magazine opening, said lever being configured to secure a removable magazine within the magazine opening. ### Claim 8 (depends on 1) The shotgun magazine receiver assembly of claim 1, further comprising: a threaded tube magazine opening disposed along the first end of the receiver body, said tube magazine opening being positioned beneath the barrel opening and configured to receive a conventional shotgun tube magazine. ### Claim 9 (depends on 1) The shotgun magazine receiver assembly of claim 1, further comprising: an ejector port disposed along one of the opposing side walls of the receiver body. ### Claim 10 (depends on 1) The shotgun magazine receiver assembly of claim 1, wherein the back end of the receiver body is configured to receive at least one of a conventional shotgun grip and a stock. ### Claim 11 (depends on 1) The shotgun magazine receiver assembly of claim 1, wherein a conventional shotgun comprises a pump action shotgun. ### Claim 12 (depends on 1) The shotgun magazine receiver assembly of claim 1, wherein a conventional shotgun comprises a semi-automatic shotgun. ### Claim 13 (depends on 1) The shotgun magazine receiver assembly of claim 1, further comprising: a removable shotgun magazine.
