Made in the USA, the PMAG 10 provides next-generation performance for those needing lower-profile magazines. 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 weapons. NOTE: This item is also compatible with HK 416/MR556A1/M27 IAR, British SA-80, FN SCAR MK 16/16S, and others.
