Magpul PMAG GEN M3 20Rd. Magazine for 223 Rem, 5.56x45mm NATO, Black (MAG560-BLK)

Made in the U.S.A, the PMAG 20 AR/M4 GEN M3 is a polymer magazine for AR15/M4 compatible weapons. 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.

It also features 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.
