This 10-round AR-style polymer magazine is compatible with firearms chambered in 5.56x45 NATO/.223 Remington. It features a long-life stainless-steel spring, four-way anti-tilt follower for reliable feeding, and an easy to disassemble flared floorplate to aid extraction and handling of the magazine while providing improved drop protection. A redesigned bolt catch notch in the rear of the magazine provides increased bolt catch clearance, while an over-travel stop on the spine helps ensure the magazine will not over-insert on compatible firearms. In addition, an included pop-off impact dust cover can be used to minimize debris intrusion and protect against potential damage to the top cartridge during storage and transit. Fits the AR-556 rifle, AR-556 pistol & Ruger American Rifle. Made in the USA by Magpul®.
