Magpul PMAG 20 AR 300 B GEN M3 300 Black Magazine

Load up with the Magpul PMAG 20 AR 300 B GEN M3, a magazine for rifles chambered in .300 Blackout. The 20-round body offers a more compact profile than standard 30-round magazines, improving maneuverability and concealment for small firearms. Built from impact- and crush-resistant polymer, it features a distinct rib design and texture to prevent cross-loading with other calibers. Aggressive front and rear texture ensures a secure grip, while the removable slim floor plate, paint pen dot matrix, and impact/dust cover add practical functionality.
