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 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 frame adapter that aid in making compatible a slide associated with a first firearm and a frame associated with a second firearm. The compatibility is such that the slide associated with a first firearm and a magazine associated with a second firearm being able to function properly as a single integrated firearm. This system includes an adapter, and one or more adapter elements that aids allowing the modular firearm to function properly.

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.

Abstract: A magazine extension comprises an extension body having an open upper end configured to be slidably coupled with an open bottom end of a magazine tube for an ammunition magazine, a retaining member, and a base plate. The retaining member is removably receivable in a passage defined through a rear wall of the extension body to releasably secure the body to the magazine tube. A portion of the retaining member protrudes out of an upper end of the passage and overlaps a rear wall of the magazine tube to limit sliding movement of the tube relative to the extension body when the tube is coupled with the body and the retaining member is received in the passage. The base plate is configured to be slidably coupled with an open lower end of the extension body and obstruct a lower end of the passage to releasably secure the retaining member in the passage.

Abstract: A collapsible, foldable container with reduced deflection and increased strength and convenience is provided. A door can be provided in the lower portion in one or more of the sidewalls, opening upward and outward without unduly loading the door hinges. A latch is provided to hold the door in the open configuration engageable by slamming open and disengaging by jerking close. In one embodiment, the base of the container includes a plate having ribbing extending upwardly therefrom. When a smooth-bottomed surface is desired, a plate may be installed on top of the upwardly extending ribbing. Ribbing on the bottom surface and/or sidewall surfaces can include close-loop or circular ribs with integral ribbing extending radially therefrom. Preferably, containers are configured so that they can be stacked, one upon the other, either with or without a top or lid. Preferably, the lid, when provided, avoids pooling of liquids such as rainwater by having a domed-shape and by providing channels in a peripheral ridge.

Abstract: A container with collapsible sidewalls is provided with a sidewall extension. The sidewall extension increases the height of the sidewall pivot axis above the container base. When the sidewalls are collapsed a portion of the container volume remains for holding, for example, packing material or dunnage.

Abstract: A container having an opening in a sidewall coverable by a hinged gate is described. The hinge for the gate is made by mating two, preferably identical, hinge bodies to thereby insert posts on the hinge into sockets residing, respectively, in the gate and sidewall. The hinge rotates with respect to the gate about a first axis, and rotates with respect to the sidewall about a second spaced parallel axis. The gate, in the opened position, lies flat against the sidewall and is entirely clear from the opening. The gate is latched in its closed position by a clip structure which passes through a first lip of the gate, then through a lip of the sidewall, then through a second lip of the gate.
