Abstract: A hybrid firearm magazine. The hybrid firearm magazine has a first section fabricated from a sheet material and a second section molded from a plastic. The first section includes a mating edge defining one or more recesses. The second section engages the mating end of the first section with the plastic filling the recesses. The mating end has nonlinear edge. The plastic fills in around the nonlinear edge of the first section to form a joint. The interface of joint prevent movement of the first section relative to the second section along the vertical and horizontal axes of the hybrid firearm magazine. The thickness of the second section at the joint is substantially equal to the thickness of the first section. Optional retention couplers improve the strength of the joint and the resistance to movement of the first section relative to the second section.

Abstract: A firearm magazine having a body constructed by a two-stage process. First, a fabrication stage shapes a sheet material into a substantially tubular magazine body with a joint having one or more retainers formed along the mating ends. Second, a molding stage joins the mating edges using a plastic that fills the joint between the mating edges. One or more retainers along the mating ends are designed to distribute forces applied to the magazine body along the seam and provide support from the sheet material to secure the connection rather than rely on the tensile strength of the filler material to maintain the joinder of the mating edges.

Abstract: A hybrid charging handle for a firearm. The hybrid charging handle includes a plastic shell attached to a metal skeleton. The metal skeleton is stamped and folded to provide strength and rigidity. The plastic shell is molded to provide the geometry fitting the firearm. The plastic shell is attached to the metal skeleton to form the hybrid charging handle. The plastic shell provides benefits such a low friction. The hybrid charging handle can be manufactured cheaper and faster than conventional charging handles and with less material waste.

Abstract: The present disclosure relates to a modular firearm control unit that aid in making compatible a slide associated with a first firearm and a frame associated with a second firearm. The compatibility made functional using a frame that includes an aperture and a rigid insert that includes a slide rail and an aperture that is compatible with the aperture found in the frame.
