DuraMag 30rd Aluminum Speed Replacement Magazine for AR-15 (Blue/Black) - .223 Rem, 300 Blackout, 5.56x45mm NATO

A DuraMag 30rd aluminum speed replacement magazine for AR-15 is built for shooters who demand reliability without compromise. Whether you're running .223 Rem, 5.56x45mm NATO, or 300 Blackout, this magazine pairs mil-spec compatibility with the durability that has made DuraMag the choice of law enforcement and military units worldwide since 2011. The aluminum construction resists the flex and swell of polymer alternatives, and the hard-coat anodizing isn't just a surface finish—the color is integral to the metal itself, meaning it won't chip, scratch off, or fade with hard use.

Built from 6061-T6 aluminum with type-III hard-coat anodizing, DuraMag Speed magazines are engineered for consistency and longevity. The robotic welding and progressive die tooling ensure that every magazine meets the same exacting standard, round after round and magazine after magazine. These are truly designed for extended loaded storage without worry; the aluminum body simply won't fail you the way lesser materials can in the field or at the safe.

The 30-round capacity fits standard AR platform receivers and delivers the round count most AR shooters prefer for range days, training, and tactical work. Available in a choice of color-anodized finishes, DuraMag magazines are as comfortable in your loadout as they are dependable when the shot matters.

Frequently Asked Questions

Will this magazine work with my AR-15?

Yes. DuraMag Speed magazines are USGI-pattern compatible with standard AR-15 platform receivers and work with .223 Rem, 5.56x45mm NATO, and 300 Blackout ammunition.

What's the difference between aluminum and polymer magazines?

Aluminum magazines like the DuraMag won't flex or swell under load or during extended storage, making them more reliable in extreme conditions and over the long term. The hard-coat anodizing is also more resistant to damage than painted finishes on inferior materials.

How many rounds does this magazine hold?

This is a 30-round magazine, the standard capacity for AR-15 shooters.

Is the color permanent?

Yes. Unlike painted or dyed magazines, DuraMag's color is integral to the anodizing process itself, so it won't chip, peel, or fade with handling and use.
