This is a ProMag 10-round magazine for DPMS SR-25 pattern AR-10 rifles in .308 Win/7.62x51mm.
These classic-style AR-10 magazines are built from heat-treated steel with chrome silicon internal springs and precision-molded polymer follower to ensure reliable feeding. 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. These 10-round magazines are ideal for target practice and bench-rest shooting. They’re made in the U.S.A. and come with a lifetime replacement guarantee, making them a perfect upgrade for your AR-10 arsenal!
