Upgrade your range kit with the ProMag ®AR-10 .308/7.62x51mm 40-Round Magazine. This aftermarket magazine is designed with a lightweight polymer construction for superior strength and features a textured gripping surface for positive handling and quick reloads. The heat-treated chrome silicon wire spring and injection-molded follower ensure smooth, reliable feeding in high-stress target and defensive environments. Keeping true to Eugene Stoner’s original design, the AR-10 delivers all the practical functions of its smaller rifle cousin (the AR-15/M-16) but with a hard-hitting, full-size battle rifle round. And the DPMS LR-308 pattern AR-10 is among the most flexible variants with the most available aftermarket support. All ProMag magazines come with a lifetime replacement warranty, ensuring you’ll always have a working magazine on hand when you need one. Order today! Made in USA.
