  1. Nice Mags - Don't Dangle
    Let's face it, stuff dangling from your rifle is never good. Stuff dangling at all, is not good. 30-round mags look cool and all, but they stick out the bottom pretty far - especially when we are neutered with 5-round limits (rifle magazines) in Canada.

    The 20-round Magpul Gen3 mags are the best of everything. Legal limit at 5-rounds and stick out just far enough to grab onto for quick changes. The Gen 3 comes with the dust cover - so you're good.

    Love 'em. Just wish they had a "Pistol" designation... Please Magpul. Please listen to us people in the frozen white north. Thanks in advance.

Magpul MAG560 PMAG 5/20 GEN M3 5.56x45

100% of 100
In stock

The next-generation PMAG 20 GEN M3 is a 20-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.

Similar to the MOE PMAG, the GEN M3 features a long-life USGI-spec stainless steel spring for commonality, 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.
