PRODUCT DETAILS

The next-generation PMAG 20 AR/M4 GEN M3 is a 20-round polymer magazine for AR15/M4 compatible weapons chambered in 5.56×45 NATO / .223 Remington. Along with expanded feature set and compatibility, the GEN M3 incorporates new material technology and manufacturing processes for enhanced strength, durability, and reliability that exceed rigorous military performance specifications.

Similar to the MOE® PMAG, the GEN M3 features a long-life USGI-spec stainless steel spring for commonality, a four-way anti-tilt follower, constant-curve internal geometry for reliable feeding, and simple tool-less disassembly for easy cleaning.

The PMAG 20 GEN M3 also includes a redesigned bolt catch notch in the rear of the magazine that 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 give 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 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.

Made in the U.S.A.

    Great mags

  2. topgunpilot (verified owner)

    I’ve had straight wall 20-round mags fail to lock open in the last round, but the curved Gen 3 PMAG 20s function perfectly.

  3. SJ (verified owner)

    Excellent mags as expected.

  4. CMack (verified owner)

    I’ve tried a lot of magazines. This 20 round magazine is one of my favorites. Like everyone, I like to keep a few of the 20 rounders for using with SPR type guns, but I also will regularly run a 20 rounder to lower bulk/visibility on rifles or in mag pouches. The M3 20 round magazine with a Taran +5 (24 rounds in the mag) has become my preferred mag setup for the initial magazine in the gun. It’s shorter than a 30 round magazine to allow for better deployment from vehicles, and other tight spaces, but still has a respectable capacity.
