ProMag AR-10 .308/7.62x51mm 50-Round Drum Magazine

Push your AR-10’s performance to the next level with the ProMag 50-round drum magazine, engineered for serious range time, tactical drills, and high-volume shooting. Designed to feed .308 Winchester or 7.62x51mm NATO rounds reliably, this drum gives you the capacity and consistency serious shooters demand.

Built from a rugged DuPont™ Zytel®-based polymer, it’s lightweight but tough enough to handle field conditions and heavy use. Reinforced with stamped steel feed lips and a steel magazine catch, this drum is made for consistent, dependable cycling. The stainless steel spring and molded polymer follower provide smooth feeding from the first round to the last.

Compatible with most AR-10 style rifles that accept LR-308 (DPMS) or SR-25 pattern magazines. Not compatible with Armalite AR-10B rifles or those using M14-pattern mags.
