The DuraMag AR-15 .223 Rem/5.56 NATO 30-Round Stainless Steel Magazine (DuraMag part no. 3023041178CPD) is built on the idea that a rifle is only as reliable as the magazine feeding it. Where polymer magazines can warp or shift under humidity and temperature swings, DuraMag’s all-metal, stainless steel construction is engineered to hold up through a sunny range day, a frozen night, desert sand, or years in long-term storage. It’s sized for AR-15-platform rifles chambered in .223 Remington or 5.56 NATO and holds a standard 30-round capacity, with an overall length of 7.9 inches. That combination of material and build quality is aimed squarely at shooters who need consistent feeding no matter what conditions the rifle sees. This magazine from DuraMag is a durable step up from standard polymer AR-15 magazines. It’s part of our AR magazines lineup.
