The DuraMag Speed AR-15 20rd magazine in .300 Blackout/.223/5.56 gives you a proven alternative to basic GI-style mags without the weight penalty or durability compromises of polymer. Built from 6061-T6 aluminum with type-III hard-coat anodizing, this gray-finished magazine delivers the durability and consistency that OEM builders, law enforcement, and military units have relied on since DuraMag entered production in 2011. Unlike cheaper anodized magazines where color is merely a surface coating, DuraMag's hues are integral to the anodizing process itself—they won't chip or fade under hard use.
The 20-round capacity makes this magazine ideal for sport shooting, home defense, or training without the bulk of larger drums or drums. Its aluminum construction stays rigid through thousands of rounds; it won't flex, swell, or warp even during extended loaded storage. The anti-tilt follower and EverFlex anti-fatigue spring work together to ensure smooth, reliable feeding and consistent round positioning, reducing jams and feed issues that can derail your day at the range or in the field.
DuraMag manufactures these magazines with progressive die tooling, precise post-and-hole engineering, and fully robotic welding—processes that guarantee consistency batch to batch. Whether you're building an AR-15 for 3-gun competition, hunting, or duty use, a DuraMag Speed magazine in your loadout means one less variable to worry about.

Yes. This magazine is designed for compatibility across .300 Blackout, .223 Remington, and 5.56 NATO, so it will function in any standard AR-15 platform chambered in those cartridges.
Aluminum won't flex or swell under load or during extended storage the way polymer magazines can. DuraMag's 6061-T6 aluminum is rigid and dimensionally stable, and the type-III hard-coat anodizing provides corrosion resistance and durability in field conditions without sacrificing weight savings over steel.
DuraMag's colors are integral to the type-III hard-coat anodizing process itself, not just a surface coating. Because of the chemical nature of anodizing, slight hue variations between individual magazines and batches are normal and do not affect function or durability. DuraMag's quality control rejects only those outside an acceptable color range.
Yes. The aluminum body and anti-fatigue spring design make this magazine safe for extended loaded storage without risk of the material degrading, warping, or losing spring tension.
