The DuraMag Speed 20rd AR-15 magazine in OD Green aluminum delivers the kind of reliability you need when you're running intermediate cartridges like .300 Blackout, .223 Remington, or 5.56 NATO. Built from 6061-T6 aluminum with a Type-III hard-coat anodized finish, this magazine is engineered to handle serious use—whether you're running suppressed subsonic loads or standard velocity rounds downrange. Unlike polymer alternatives, aluminum won't flex, swell, or degrade under prolonged storage, and the anodized color is integral to the metal itself, not a thin coating that wears away.
DuraMag's reputation stems from two decades of supplying magazines to military, law enforcement, and OEM platforms worldwide. The Speed design incorporates a black anti-tilt follower and EverFlex anti-fatigue spring to ensure reliable feeding and consistent performance across thousands of rounds. Progressive die tooling, robust post-and-hole geometry, and fully robotic welding mean you get the same fit and function every time—no surprise malfunctions because of manufacturing variance. This is a magazine that runs the same on day one and day five thousand.
The OD Green finish is practical and professional. It's integrated into the anodizing process, so it won't chip or peel like paint, and it blends seamlessly with modern tactical rifles and carbines. Whether you're building a 5.56 rifle, a dedicated .300 BO upper, or rotating between platforms that share the same magazine pattern, the DuraMag Speed 20-rounder is a workhorse that earns its place in your mag rotation.

| Caliber Compatibility | .300 Blackout, .223 Remington, 5.56 NATO |

Yes. DuraMag Speed magazines are compatible with .300 Blackout, .223 Remington, and 5.56 NATO across standard AR-15 platforms.
Aluminum is superior for extended loaded storage. It won't flex, swell, or degrade over time the way polymer can. The hard-coat anodized finish is also more durable against temperature swings and UV exposure.
No. The color is part of the Type-III hard-coat anodizing process, integrated into the metal itself. It won't peel or flake like paint.
DuraMag Speed magazines use progressive die tooling, robust post-and-hole geometry, fully robotic welding, and a quality-controlled manufacturing process that ensures consistency every time. The anti-tilt follower and EverFlex spring also improve reliability and reduce feed failures.
