A sling is held in a folded state under a cheek piece attached to the butt of a rifle or gun stock, and deployed by drawing from the cheek piece and attaching to a forward end of the rifle or gun. A rear sling end may remain attached to the rear of the rifle or gun at all times. The folded sling is stowed in a channel formed beneath the cheek piece by a releaseable flap, with a forward sling end exposed at the rear of the channel. The sling is deployed by drawing from the rear of the channel and then reaching forward to attach to the forward end of the rifle or gun. The sling may be returned to the folded state by folding the sling, releasing one side of the flap, placing the folded sling under the cheek piece, and reattaching the flap.
