This polymer magazine with a 10-round capacity, is designed in the AR-style and is fully compatible with firearms chambered in 5.56x45 NATO/.223 Remington. It incorporates a long-lasting stainless steel spring, a four-way anti-tilt follower for impeccable feeding reliability, and an easily disassembled flared floorplate that aids in extraction, handling, and provides enhanced drop protection. A rear bolt catch notch has been redesigned to grant greater bolt catch clearance, and an over-travel stop on the spine contributes to preventing over-insertion on compatible firearms. Furthermore, it comes with an impact dust cover that can be easily popped off, safeguarding the top cartridge from debris intrusion and potential damage during storage and transportation. This versatile magazine is suitable for the AR-556 rifle, AR-556 pistol, and Ruger American rifle. Proudly crafted in the USA by Magpul.
