Abstract: A modular firearm magazine assembly that is adapted to accept a “plug” piece to restrict and reduce the number of cartridges that can be contained in a magazine housing. The assembly in one construction is comprised of a base plate retainer collar, base plate, resistance spring, and cartridge follower plate that attach to and mount inside a cartridge magazine housing. In alternative constructions, the base plate and cartridge follower plates are modified to provide plug pieces that cooperate to restrict and limit the maximum possible travel distance of the cartridge follower plate to reduce the cartridge storage capacity of the magazine and accommodate governmental regulations.

Abstract: A game call having a box piece and a striker piece that contacts and vibrates an exposed edge of at least one box wall to produce sound. The box includes a bottom wall and a plurality of side and end walls that circumscribe an open-sided sound chamber. An appendage or striker pivot post projects from the box and supports a resilient assembly to bias the striker to the pivot post. The striker includes a slotted keyway having an aperture, a channel way and an adjoining recess that supports the pivotal movement of the striker. Striker pieces constructed to various shapes and from a variety of materials and having one or more keyways or deformable retainer assemblies are shown that can be interchanged with the box piece to produce a variety of different sounds.
