Abstract: A magazine is provided for housing a predetermined number of rim-fire cartridges in a double column configuration with minimal magazine width and length requirements. The magazine is configured so that the rims of the cartridges are automatically placed in a nested or staggered relationship when they are inserted and are maintained in that relationship as they move through the housing, so as to prevent cross over of the rims and jamming. The nested, side-by-side positional relationship of the cartridges in the magazine is changed to a single file relationship while the lateral force exerted on the cartridges is controlled and jamming caused by friction or deformation is prevented. The magazine has an arcuate shape with one end wall having a portion defined by a radius of about 5.29 inches. Three rails are positioned on the upper portion of one side wall. Rails and baffles are configured to avoid or reduce interference of debris or wax build-up.

Abstract: A number of rifle parts are provided to improve the appearance, facilitate the assembly/disassembly, and/or ease the carrying of a conventional rifle. In a preferred application one or more of the rifle parts are used with a 22 caliber rifle. The rifle parts include a handle unit that can be added to the conventional rifle and which is separate and detachable from the rifle body. The handle unit can be connected to the rifle body using fasteners or a dovetail arrangement. The handle unit preferably includes aligning holes through which the shooter can see the original rifle sight at the free end of the rifle barrel. A front sight assembly is provided in which a front sight is elevated to be in alignment with the rear sight. The front sight assembly makes use of the original sight or the sight slot to maintain the proper sight line between the rear sight and the front sight. A barrel retaining assembly is also provided which can be substituted for the conventional barrel retaining device.

The nested, side-by-side positional relationship of the cartridges in the magazine is changed to a single file relationship while the lateral force exerted on the cartridges is controlled and jamming caused by friction or deformation is prevented. A split follower device having two followers which are movable with respect to each other is provided to maintain an upward bias on the cartridges throughout their movement through the magazine.
