The ProMag AR-15 Drum Magazine (brand part no. DRMA123) holds 120 rounds of 5.56mm/.223 ammunition in a compact drum body built from a proprietary DuPont Zytel-based polymer. ProMag reinforces the feed lips and magazine catch with over-molded stamped steel for durability, and an injection-molded follower works with a magazine spring formed from heat-treated chrome silicon wire for reliable feeding. Made in the USA, this drum fits standard AR-15 platforms chambered in 5.56mm or .223. Among rifle magazines, this ProMag drum favors AR-15 shooters who want extended capacity without swapping to a belt-fed setup.
