Combining an extended capacity with lightweight polymer construction and chrome silicon internal springs, these ProMag enhanced magazines deliver combat-ready performance at a price that's hard to beat. 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 guarantee, ensuring you'll always have a working magazine on hand when you need one.
