The Magpul PMAG GEN M3 30-round magazine for AR-15, M4, and M16 platforms is a workhorse polymer mag built to handle the demands of the range, competition, and field. Whether you're running a standard Colt-spec rifle or something less common, this next-gen PMAG delivers the reliability you need without fuss. It's made in the USA with impact-resistant polymer and modern manufacturing that far exceeds military performance standards—the kind of magazine you grab when you want one that simply works.
The GEN M3 design balances proven features with real-world improvements. Its constant-curve internal geometry feeds .223 Remington and 5.56 NATO ammo smoothly, while the anti-tilt follower and long-life stainless steel spring handle thousands of rounds. The redesigned rear bolt catch notch gives you more clearance, and an over-travel stop prevents the magazine from jamming during insertion on compatible weapons. You get tool-less disassembly for quick cleaning, a paint-pen dot matrix on the base so you can mark loads at a glance, and new low-profile ribs plus aggressive front and rear texturing for confident handling in wet, dusty, or cold conditions.
Capacity and fit matter too. At 30 rounds with a max length of 7.5 inches, this magazine fits comfortably in standard double and triple pouches—Magpul slimmed down the floorplate without sacrificing durability or the flared design that makes extraction and reloading faster. Beyond AR-15s, the modified geometry also supports wider STANAG 4179 compatibility, including HK 416, FN SCAR MK 16/16S, SA-80, and other modern platforms.
