The new and improved AR-STONER™ AR-15 Magazine features a stronger Stainless Steel Body for longer service life and greater resistance to damage than the traditional, aluminum bodied AR-15 magazine. The Enhanced Anti-Tilt Follower and Chrome Silicon Spring contribute to reliable feeding, even after long term storage fully loaded or prolonged use. Made to Military Specifications, the AR-STONER™ AR-15 Magazine can be counted on to perform reliably at the range, in competition, or in the field.
