Springs formed from non-round wire stock for a detachable magazine for a firearm are disclosed. A detachable magazine may have a body having a base, an ammunition follower positioned within the body, and a spring formed from wire having a non-round cross-section positioned between the body and the follower. The non-round wire provides a shorter compression height for the spring when compared to traditional round wire springs currently used in detachable firearm magazines.

A shotgun ammunition conversion system has a detachable magazine well having a sleeve defining a rectangular passage adapted to removably receive an ammunition magazine, a boss extending forward of the sleeve and at a level above at least a portion of the sleeve, the boss being adapted to be received in the rear aperture of the magazine tube, and a tang extending rearward of the sleeve and defining a tang aperture operable to receive a fastener associated with a shotgun frame to secure the magazine well to the shotgun with the sleeve proximate and aligned with the loading port when the boss is received in the rear aperture of the magazine tube. The boss may have a lower cylindrical surface portion operable to contact a lower portion of the magazine tube adjacent to the rear aperture. The boss may be a cylindrical body.

An ammunition storage and a magazine loading/unloading device for weapons. The apparatus provides for the rapid loading of ammunition into a magazine used for holding a number of rounds of ammunition. It is comprised of a loader body having a reservoir section, having a magwell section, and a connecting way to receive an ammunition magazine, and having a manner for connecting the magwell section to the reservoir section; an essentially rectangular block which slidably interfaces with the essentially rectangular inner space of the loader body and the rectangular block with an aperture for receiving a plunger handle; and a spring retaining clip to hold the ammunition in the inner space of the loader body. The device loader body can be a single or alternatively a two piece reservoir assembly and can be used as an unloading device as well.

The inventive technology herein describes an improved magazine extension configured to be coupled with an ammunition magazine for a firearm. In one embodiment, the improved magazine extension may include an indexing channel to facilitate a more efficient and accurate indexing of the magazine into the firearm. Additional embodiments may include an improved magazine extension having an increased ammunition capacity, as well as a quick release catch to enable the efficient removal of a magazine from the firearm.

A lower receiver assembly of a rifle including a lower receiver having a magazine well formed thereon between a distal end and a proximal end, the lower receiver operable to receive a trigger assembly including a trigger, a hammer, and a firing pin. The lower receiver can include an operating rod retention tab coupled with an upper surface of the receiver and the operating rod retention tab extends above the upper surface and is operable to be received in a groove formed in a receiver of an upper receiver.

A practice magazine includes a housing that at least partially houses one or more weights, a rotating or pivoting follower, and a spring for biasing the follower in a first direction that is toward the slide of a firearm when the practice magazine is positioned in the magazine compartment of the firearm. The housing also includes a magazine catch notch and additional features to cooperate with the firearm magazine compartment's geometry. The follower attaches to the housing at a pivot support around which it can rotate, and the housing and follower include a stopper arrangement that limits excessive rotation of the follower. The spring, disposed between the follower and housing, produces tension when the practice magazine is fully inserted into the magazine compartment of the firearm. The weights are disposed in the housing to mimic the weight of loaded ammunition.

Magazines with guard elements have a tubular body having a lower end and an upper end and defining an interior space, the body having opposed lateral sidewalls, and opposed front and rear walls, at an intermediate portion along the length of the body between the upper and lower ends, a sidewall defining a magazine catch opening, the magazine catch opening having an upper limit including a downwardly-facing ledge surface configured to engage a latch, and a recessed guard element at the magazine catch opening configured to prevent intrusion of the firearm latch into the interior space. The recessed guard element may protrude into the interior space. The tubular body may have a wall thickness adjacent to the recessed guard element, and the recessed guard element may have the same wall thickness. The tubular body may be formed of an articulated sheet.
