Magpul PMAG 10 AR/M4 GEN M3 Magazine - 5.56x45mm NATO / .223 Remington, 10-Round Capacity - Impact-Resistant Polymer, Four-Way Anti-Tilt Follower - Black - MAG559-BLK
Product Description
Whether you live in a location with strict capacity laws, or you just need a shorter magazine that won't dig into the ground while shooting from a bench or a bipod, standard 30-rounders can get in the way. The **Magpul® PMAG® 10 AR/M4 GEN M3™ Magazine (MAG559-BLK)** is designed to give you the exact same professional feeding reliability as Magpul's full-size magazines, but in a compact, low-profile 10-round housing that stays out of your way.
This is a genuine GEN M3 magazine, meaning Magpul built it from their toughest, next-generation impact-resistant polymer formula. It can handle hard drops on gravel, extreme heat, and rough use without cracking. Inside, it features a long-life stainless steel spring and a bright four-way anti-tilt follower. This ensures that every round feeds at a perfect angle into your upper receiver, eliminating the nose-diving jams that often plague cheap steel or unbacked aftermarket options. The slim design fits easily into any standard AR-15 magwell and drops completely free the instant you hit the release button.
The baseplate is designed to be slim and easy to remove for regular cleaning, yet wide enough to give you a secure grip when pulling it from a pouch. Magpul also added a paint pen dot matrix onto the lower side panels, allowing you to easily mark the magazine with your initials or load type. It is a rugged, reliable tool that is perfect for hunting, precision target shooting, or compliant home defense rigs.
*Armorer Bench Notes & Real-World Field Guidance: This 10-round GEN M3 PMAG arrives clean and ready to load right out of its factory wrapper. EXTENSIVE PLATFORM COMPATIBILITY: While optimized natively for standard AR-15/M4 rifles chambered in 5.56x45mm NATO and .223 Remington, the GEN M3 internal geometry is modified to fit a wide range of non-standard platforms. It functions flawlessly in the HK416, British SA-80, FN SCAR 16, and custom bolt-action chassis systems that accept standard AR-15 magazines. It is also an excellent option for loading alternative calibers like .300 AAC Blackout. Dust Cover Protection: This model comes packaged with a removable impact-resistant top dust cover. When snapped on, it seals out field dirt and sand while pressing down slightly on the top cartridge to take storage tension off the feed lips. Workbench Maintenance: Cleaning after a dirty day at the range is simple. Just compress the detent pin on the bottom plate, slide the floorplate off, and pull out the spring and follower assembly. Wipe the inside of the polymer shell clean with a dry rag. Never apply wet gun oil or grease inside a PMAG; a dry internal environment ensures loose carbon soot won't turn into a sticky sludge that bogs down the spring mechanism downrange.*
