The .308 Win. caliber magazine for the Ruger® Scout Rifle is constructed of durable glass-filled nylon with a stainless steel spring. A snap-on dust cover is included which helps keep the magazine internals clean and allows long-term storage of the magazine while loaded. The three-round magazine fits near-flush; the base-plate is exposed when the magazine is loaded in the rifle. Not recommended for use with other M24/M40/AICS-style systems.
