Magpul PMAG GEN M3 5.56x45mm NATO/.223 Rem 30-Round Polymer AR-15/M4 Magazine - Coyote Tan

The Magpul PMAG 30 AR/M4 GEN M3 is a 30-round polymer magazine purpose-built for AR-15, M16, and M4 pattern rifles chambered in 5.56x45mm NATO / .223 Remington. Finished in Coyote Tan and manufactured in the USA, the GEN M3 platform brings the next generation of Magpul's flagship AR magazine to the range, the patrol car, and the duty rifle.

Inside the body, the PMAG 30 GEN M3 uses a constant-curve internal geometry that promotes smooth, reliable feeding across a wide range of ammunition and platform builds. An anti-tilt, self-lubricating follower keeps every round stacked straight and feeding consistently, while the reinforced polymer construction shrugs off impacts, solvents, temperature swings, and harsh field conditions without the corrosion concerns of a metal magazine.

The GEN M3 exterior is built for real-world handling. Ribbed gripping surfaces and aggressive front and rear texture give the mag a positive purchase during rapid reloads, and paint pen dot matrix panels molded into the bottom of the body make it easy to mark, identify, and color-code magazines at a glance. A pop-off impact / dust cover keeps debris and grit out of the feed lips, and flared floor plates speed mag changes and field disassembly. A reinforced mag catch and over-insertion stop round out the platform-specific upgrades that have made the GEN M3 the standard-issue polymer magazine for countless AR-pattern rifles.

Designed as a direct replacement for standard 30-round AR magazines, the MAG557-MCT is a workhorse 30-round magazine ready for range training, duty use, or home-defense builds. Whether you run a flat-top AR-15, an M4 carbine, or an M16-pattern rifle, the PMAG 30 GEN M3 delivers the reliability Magpul is known for in a lightweight, coyote-tan package.
