Magpul PMAG GEN M3 LR / SR 308 / 7.62×51 AR-10 20-Round Magazine For Sale

This is a Magpul PMAG Gen M3 20-round magazine for AR-10 rifles chambered in 7.62mm/.308 Win

Magpul’s next-generation M3 PMAGs are crafted from ultra-durable improved polymer with stainless steel internal springs and 4-way anti-tilt followers for consistent feeding in even the most extreme environments.

Magpul’s groundbreaking PMAG Gen M3 delivers lightweight, reliable performance for heavy-duty AR-10 battle rifles. Weighing less than half as much as standard steel magazines, PMAGs are the gold standard for combat-ready polymer magazines with a service life that nearly outlasts the weapon itself. Other features include tool-less disassembly and flared floorplates, slimmer than previous versions and perfect for use with chest rigs and magazine carriers.

Designed for use with DPMS LR/SR-25 style AR-10 rifles (will NOT work with Armalite AR-10B/Springfield M1A platforms), these magazines are constructed from durable polymer with an optional window, aggressive texturing and flared floorplates for easier reloads and disassembly. Other M3 features include a new over-insertion stop and paint pen dot matrix for easier labelling.
