A holder for supporting a long-barreled gun in a vehicle comprises a base and a holder, whereby the base may be removably coupled to the cup holder of a vehicle and the holder is adapted to support the stock of a long-barreled gun. The holder may be adjustable so as to snugly receive various sizes of gun stocks and may be covered in a cushioning material. The height of the holder relative to the base may be adjustable. The base may include one or more cavities adapted for holding bullets. The holder may include a selectively releasable retainer for retaining the stock of the gun in the holder. A method and kit for mechanically coupling two or more gun holding devices so as to prevent movement of one gun holding device relative to the other gun holding devices is also provided.

A sling attachment device has a body having a strap facility adapted for attachment of a sling strap, a flexible elongated tether having a first end attached to the body, the tether having a free end opposite the first end, and the body defining a receptacle operable to receive the free end of the tether, such that the tether may be threaded through an aperture on a rifle and received by the receptacle to secure the strap to the rifle. The tether may have a selected first width along at least a portion of its length, and the free end may have a second width greater than the first width. A ball may be attached to the free end. The body may define a channel having a width larger than the first width and smaller than the second width. There may be an aperture adjacent to the channel.
