Abstract: Disclosed is a connector for hingedly mounting a buttstock to a receiver of a rifle having a fixed hinge portion having a receiver side and an interface side, a threaded protrusion integrally formed with the fixed hinge portion and extending from the receiver side of the fixed hinge portion, a threaded ring sized in relative proportions to threadably interface with the threaded protrusion, and a buffer hole extending from the interface side, through the fixed hinge portion, and through the threaded protrusion. The threaded protrusion can be threadably received in the receiver of the rifle and the threaded ring can be configured to be threadably tightened about the threaded protrusion and against the receiver. The threaded ring can have a threaded inner surface, an outer surface, and a first and second sides. The outer surface can have a first and second raised portions separated by a notch.

Abstract: Disclosed is a device for loading a cartridge into a magazine having a cartridge loader ramp and a magazine guide. A guide pin can connect the magazine guide to the cartridge loader ramp such that the magazine guide is slidably connected to the cartridge loader ramp about the guide pin. The device can further have a base and the cartridge loader ramp can be inclined with respect to the base. The cartridge loader ramp can have a top and a foot can be disposed on the top of the cartridge loader ramp. When a magazine is inserted in the magazine guide and pressed down, a cartridge on the cartridge ramp can partially compress the magazine spring. The foot can push the cartridge into the magazine. An adapter sleeve can resize the magazine guide for use with a variety of magazines.

Abstract: Disclosed is a device for loading a cartridge into a magazine having a cartridge loader slide, a channel in the cartridge loader slide, a magazine guide, and a pin disposed in the channel and connecting the magazine guide to the cartridge loader slide. An adapter sleeve can have an inside surface for receiving the magazine and an outside surface for mating with the magazine guide. The outside surface of the adapter sleeve can be sized in relative proportions to be received in the magazine guide and the inside surface of the adapter sleeve can be sized in relative proportions to receive the magazine.

Abstract: Disclosed is a magazine loader having a base, a groove of the base, a cartridge loader slide, a channel in the cartridge loader slide, a mating portion of the cartridge loader slide sized in relative proportions to mate with the groove in the base, a magazine guide, a pin connecting the magazine guide to the cartridge loader slide; and a housing partially covering the magazine guide.
