Description
The DURAMAG Speed changes what a 20-round magazine can do. Instead of the traditional straight body, these magazines follow the curve of a standard 30-round design. That curve matters because it creates enough internal space for a full-size anti-tilt follower, which keeps your rounds perfectly aligned as they feed into the chamber. With older straight-bodied 20-rounders, rounds would dive and cause jams. The Speed design eliminates that problem with a geometry that almost completely stops feeding failures.
The body is built from 6061-T6 aluminum and type-III hard-coat anodized, so the pink color is part of the metal itself, not a coating that chips or wears off. The construction uses progressive die tooling, post and hole design, and full robotic welding, which means every magazine comes out consistent. You get a black polymer follower designed specifically for this capacity and caliber to maintain level feeding throughout the mag's life.
DURAMAG Speed Magazine Features for Reliable Performance
Inside you'll find the EverFlex anti-fatigue spring, which maintains tension whether you're running the mag at full capacity or keeping it loaded in storage. T-360 coating on the interior keeps friction low for smooth loading and provides corrosion resistance. The black follower won't shift or tilt, even during aggressive reloads or when carrying the mag on your kit.
Perfect Size for Prone, Bench, and Tactical Use
The 20-round capacity gives you a shorter, lighter package compared to a 30-rounder, making it ideal for bench shooting, sighting work, or situations where you want something less bulky on your belt. The curved body still provides good grip surface and the familiar feel of a full-size magazine without the overall length penalty.
These magazines are safe for indefinite loaded storage without worrying about flex or swell like you would with polymer. Built to handle 5.56 NATO, .223 Remington, and .300 AAC Blackout, the Speed mag has seen duty with OEM, law enforcement, and military units since DURAMAG started production in 2011. Whether you're working on accuracy, running drills, or just want a reliable compact mag for your AR, the Speed delivers consistency every time.

Frequently Asked Questions
What makes the DURAMAG Speed 20-round magazine different from a regular straight-body 20-rounder?
The Speed magazine follows the curve of a 30-round mag instead of running straight, which lets it use a full-size anti-tilt follower. Traditional straight 20-rounders often have feeding issues because rounds dive during feed. The curved design and proper follower geometry prevent those jams and keep rounds aligned throughout the mag's life.
Can I use this magazine for 300 AAC Blackout?
Yes. This magazine is designed to work with 5.56 NATO, .223 Remington, and 300 AAC Blackout. The follower and spring are specifically tuned for this capacity and caliber mix, so it handles subsonic and supersonic 300 Blackout loads reliably.
Is the pink color durable or will it chip off?
The pink is part of the type-III hard-coat anodizing process, not a painted coating. This means the color is integrated into the aluminum itself. While anodized finishes will develop patina and cosmetic wear over time with use, the color won't chip off in layers like paint would.
Is it safe to keep this magazine fully loaded in storage?
Yes. The EverFlex spring maintains consistent tension indefinitely, and aluminum won't flex or swell like polymer magazines. You can keep the magazine loaded without worrying about damage to the feed lips or loss of spring tension.
