Featuring next-gen polymer construction with USGI-spec stainless steel springs, special anti-tilt followers and constant curve internal geometry, Magpul's Gen M3 PMAG magazines are among the best and most reliable combat mags in the world today.

Improving on excellence and the gold standard in rifle magazines, Magpul’s “Gen M3” PMAG combines the rugged reliability that PMAGs are known for with a few additional features that make the world’s most trusted combat magazine even better …

20-round PMAGs offer the best of both worlds thanks to their compact, lightweight form factor and impressive capacity. With all the same features of a full-sized Gen M3 PMAG—from the paint pen dot matrix to the aggressive texturing, and more—these 20-round magazines pack a practical punch and are the perfect addition to your AR arsenal.

Modified internal and external geometry also permits operation with a wide range of non Colt-spec platforms such as the HK® 416 and MR556A1, M27 IAR, British SA-80, FN® SCAR™ MK 16/16S, and others. 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.
