Ruger AR-556 10rd 223 Rem/5.56x45mm Blued Steel Magazine

The Ruger AR-556 Magazine (part number 90384) is a factory 10-round detachable box magazine built specifically for the Ruger AR-556 and Ruger SR-556 rifle families. Designed for 223 Rem / 5.56x45mm NATO use, this magazine is constructed from durable blued steel with a black protective finish and features a high-visibility orange follower for quick round-count confirmation and reliable feeding.
