A magazine for a firearm such as long guns comprises a housing defining a cavity for holding a double staggered stack of cartridges and spring-biased tiltable follower for dispensing the cartridges into the action of the firearm. Features include an accordion type flat spring specially configured to fold into a flat condition in which adjacent bends of the spring are arranged side-by-side to reduce the folded height of the spring. The follower includes bosses slideable in mating vertical housing slots to guide the follower upward/downward motion and allow front to rear tilting action. A coupling mechanism includes a plurality of interlocking mounting teeth forming a selectively interlocked arrangement for detachably assembling the floor plate to magazine housing. A resilient snap fit tab on the floor plate secures the coupling. The magazine is longitudinally elongated and configured to fit flushly with the underside of the firearm when mounted.

Disclosed herein is a multiple shot projectile stun gun. The multiple shot projectile stun gun may include a dual-barrel stun gun comprising a first barrel and a second barrel. Further, the multiple shot projectile stun gun may include a magazine and a magazine-receiving cavity. Further, the magazine may include a first clip assembly and a second clip assembly, each including a tubular body and a drive mechanism. The tubular body may include an open end and a closed end. Further, the drive mechanism may be positioned within the tubular body. Furthermore, the tubular body of the first clip assembly may be laterally connected along the tubular body of the second clip assembly. Additionally, the open end of the first clip assembly may be positioned coincident with the first barrel. Further, the open end of the second clip assembly may be positioned coincident with the second barrel.

A detachable box magazine for firearms includes a hollow magazine tube extending longitudinally along a median plane. The magazine tube defines a single-stack portion extending to an upper tube end with an upper tube opening. The magazine tube defines a double-stack portion positioned below the single-stack portion and extending to a bottom tube end with a bottom tube opening. For example, front portions of the opposite tube sidewalls have a stepped shape between the upper tube end and the double-stack portion, and the rear portions of the sidewalls have a linear taper between the upper tube end and the double-stack portion.

A cased telescoped cartridge that includes a cylindrical case surrounding a projectile, a front end through which the projectile exits when the cased telescoped cartridge is fired, and a thermal protective insert located at the front end. The thermal protective insert insulates the cased telescoped cartridge from heat emanating from a barrel of a firearm into a chamber of a firearm when the cartridge is loaded into the chamber of the firearm. The thermal protective insert is made up of at least one thermally insulating material, and is integrated into the front end of the cased telescoped cartridge.

A housing for a cartridge magazine for a firearm including an interior space consisting of a first and a second region. Between the first and the second region a transitional region is formed which connects the first and second region with one another. The inside surface of the front wall extends in the direction of the Z-axis in at least one region along a first circular path, the inside surface of the rear wall extends in at least one region in the direction of the Z-axis along a second circular path. The first region is designed for accommodation of four stacks of cartridges arranged directly adjoining one other and preferably offset in Z-direction relative to one another. The second region being designed for accommodation of two stacks of cartridges arranged directly adjoining one another and preferably offset in Z-direction relative to one another.

A firearm magazine and a corresponding bolt carrier assembly are provided herein. The firearm magazine includes a magazine body, with the magazine body having a width to accommodate a double stack of cartridges in a zigzag pattern. The firearm magazine also includes a spring coupled to a follower within the magazine body. The magazine body also includes two feed lips coupled to the magazine body, where the two feed lips together hold a single cartridge in place in a center of the magazine body to allow a bolt carrier to push the single cartridge out of the firearm magazine and into a chamber of a firearm. The bolt carrier includes feed lip channels configured to accommodate the feed lips therein. A cocking surface is located between the feed lip channels and has a width of less than 0.400 inches.
