ABSTRACT:
A rotary feed magazine for a pump action shotgun has circumferentially arranged chambers loaded with shells, the magazine being releasably attached to the shotgun such that the chambers can be successively rotated into alignment with a receiver chamber by a slide action cam actuator mechanism which takes the place of the conventional pump action mechanism of the gun; and when each magazine chamber is aligned with the receiver chamber the slide action mechanism will control successive advancement or feeding of the shells from the magazine chamber under the urging of a plunger. A cam is activated in response to depletion of the shells in each chamber to move into the path of movement of the cam actuated mechanism whereby to impart rotation to the magazine in order to advance the next loaded chamber in succession into alignment with the receiver chamber.
