The next-generation Magpul PMAG 10 GEN M3 is a true 10-round polymer magazine for AR15/M4 compatible weapons chambered in 5.56×45 NATO / .223 Remington. Along with an expanded feature set and compatibility, the GEN M3 incorporates new material technology and manufacturing processes for enhanced strength, durability, and reliability. The PMAG 10 provides next-generation performance for those needing lower profile magazines.

The PMAG 10 GEN M3 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.

While the GEN M3 is optimized for Colt-spec AR15/M4 platforms, modified internal and external geometry also permits operation with a range of additional weapons such as the HK® 416/MR556A1/M27 IAR, British SA-80, FN® SCAR™ MK 16/16S, and others.
