This PMAG GEN M3 5.56/.223 10 round magazine incorporates new material technology and manufacturing processes for enhanced strength, durability and reliability. Modified internal and external geometry also permits operation with a range of additional weapons such as the HK416/MR556A1/M27 IAR, British SA-80, FN SCAR MK 16/16S and others. Each magazine comes with a long-life stainless steel spring and four-way anti-tilt follower for reliable feeding. The easy to disassemble flared floorplate aids with extraction and handling of the magazine while providing improved drop protection. The redesigned bolt catch notch in the rear of the magazine provides increased clearance. An over-travel stop on the spine helps ensure the magazine will not over-insert on compatible weapons. Includes a pop-off impact/dust cover to minimize debris intrusion and protect against potential damage to the top cartridge during storage and transit. MADE IN THE U.S.A.
