Product Description

The next-generation PMAG 40 GEN M3 is a 40-round 5.56x45 NATO (.223 Remington) polymer magazine for AR15/M4 compatible weapons. Along with expanded feature set and compatibility, the GEN M3 incorporates new material technology and manufacturing processes for enhanced strength, durability, and reliability to exceed rigorous military performance specifications.

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.

The PMAG 40 GEN M3 features a long-life stainless steel spring, four-way anti-tilt follower and constant-curve internal geometry for reliable feeding, and simple tool-less disassembly to ease cleaning.

In addition, 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. Low profile ribs and new aggressive front and rear texture gives positive control of the GEN M3 in all environments, and a paint pen dot matrix has been added to the bottom panel of the body to allow easy marking by the end user for identification. The new, easy to disassemble flared floorplate aids extraction and handling of the magazine while providing improved drop protection, but is slightly slimmer than before for better compatibility with tight double and triple magazine pouches. An included pop-off Impact/Dust Cover can optionally be used to minimize debris intrusion and protect against potential damage to the top cartridge during storage and transit.
