STOCK COVER-RIFLE Rubberized ammo loops sized for 6 Rifle Shells. The Stock Cover is a "must have" for all hunters. The Stock Cover uses rubber backed elastic loops that help keep ammo firmly in place and convenient for rapid deloads. Op/Tech uses quality grade neoprene for superior protection against impact and abrasion, as well as extra cushion and increased comfort against the face. Another benefit is that the neoprene can stretch over the butt of the stock so you don't have to remove your scope to put it on.
