The present invention relates to a magazine extension which has been developed for use in semi-automatic and pump-action hunting rifles and which increases the magazine capacity without losing spring force by easily connecting the end of the rifle to the magazine tube.

The present disclosure provides apparatus and methods for coupling an item to another item. The apparatus comprises a coupler mounted on the item and comprising a mating face having a plurality of catches thereon, the plurality of catches comprising at least one complementary pair of catches positioned and shaped to be engaged with corresponding catches of another coupler having an identical mating face when mating faces of two couplers are facewise engaged with and rotated relative to each other to align with each other. The coupler may be implemented as a floor plate of a magazine, as a clip, or in other forms.

A firearm magazine case that is sized to hold a stack of firearm magazines, which case includes a spring mechanism at one end such that the magazines are advanced within the case to a ready position as the magazines are extracted from the case and configured to be mounted on a person's front or side so that the magazines are reached with an easy and natural motion, whereby the case is contoured to a person's body and is configured such that magazines are able to be extracted in one step, yet are effectively protected from the environment, the case includes an attachment mechanism that allows the case to be mounted either horizontally or vertically, according to the user's preference, the case's attachment mechanism, which consists of an “x” shaped ridge or lip which coordinates to accept a triangular insert that is attached to a person's clothing, whereby sliding any side of the “x” down over the triangle attaches the case in a secure manner, yet allows the case to be quickly and easily detached and/or replaced with a new magazine dispenser, and the case is stackable (and perhaps joiningly stackable) with other cases.

The present invention relates to a gun (1) with a pair of barrels (6′, 6″) flanking each other, each delimiting a cartridge chamber (12′, 12″). The gun further comprises a pair of firing pin tips (8′, 8″) for a cartridge (10′, 10″), movable towards the cartridge chambers (12′, 12″) by means of a firing device operated by a trigger (4′, 4″); such device acts on the firing pin tips to allow a substantially simultaneous advancement thereof. The invention also relates to a two row magazine for a double barrelled gun.

A magazine sleeve, including: a fixing member, which is a sleeve case having a U-shaped cavity, and a notch of the adjusting member is arranged at the opening of the sleeve case, and an adjusting slide is disposed at the notch of the adjusting member and perpendicular to a back plate of the notch of the adjusting member, and a through hole is provided with a connecting rod on the back plate; the adjusting member, is a U-shaped slot buckle plate which is located at the notch of the adjusting member. An elastic slide of the U-shaped slot buckle plate matches with the adjusting slide of the back plate, and an adjusting receiving cavity of the magazine is formed when the U-shaped slot buckle plate cooperates with the back plate.
