This DuraMag Speed magazine (mfr. part no. 2023002175CPD) holds 20 rounds of 5.56 NATO/.223 Remington (also compatible with .300 AAC Blackout, which shares the same case dimensions) and improves on the standard USGI aluminum AR-15 magazine pattern. The 6061-T6 aluminum body is Type III hard-coat anodized in a gray-and-black finish, with the color built into the anodizing process itself rather than an applied coating, so it won’t wear off like painted alternatives. DuraMag has supplied these to military, law enforcement, and OEM customers since 2011, and they’re rated safe for long-term loaded storage without flexing or swelling the way polymer bodies can.
