DuraMag USGI Magazine Features The DuraMag USGI magazine follows the time-tested USGI pattern a design trusted by military and civilian shooters alike for its reliable feeding and broad compatibility with 5.56 NATO and .300 Blackout AR platform rifles. Speed bodies are constructed from 6061-T6 aluminum a lightweight yet strong alloy that holds its shape under repeated loading and unloading. Type-III hard-coat anodizing gives the magazine body a hard wear-resistant surface that protects against scratches and corrosion through years of use. Because the magazines are metal rather than polymer they remain safe for extended storage while loaded without the risk of flexing or swelling that can affect some polymer-bodied magazines. Unlike magazines that rely on an inferior surface coating to add color DuraMag s OD Green finish is part of the anodizing process itself meaning the color is bonded directly into the metal rather than sitting on top of it. This approach ensures the finish will not chip peel or wear away from repeated handling and reloading. With a 10 round capacity this magazine suits shooters in restricted-capacity states or those who prefer a lower profile magazine for certain rifle configurations. The DuraMag USGI 10 round magazine is available for sale at GrabAGun for AR platform owners who want a proven durable aluminum magazine.
