DuraMag SS 30-Round AR-15 Magazine - Black with Orange Follower, Fits .223 Rem, 300 Blackout, 5.56x45mm NATO

The DuraMag SS 30-round AR-15 magazine is built for shooters who demand reliability in conditions where lesser magazines fail. Whether you're running through drills at the range, hunting in variable weather, or keeping ammunition staged for the long term, this all-steel magazine delivers the dependability your rifle deserves. Unlike polymer designs that can warp, crack, or lose shape under temperature swings and humidity extremes, DuraMag's steel construction holds its form and function through decades of use—from scorching desert days to frozen mountain nights.

The orange anti-tilt follower keeps rounds stacked straight and feeding reliably into your chamber, shot after shot. The Everflex spring maintains consistent spring force without losing tension, so your last round feeds as cleanly as your first, even after hundreds of loadings. This magazine works across the most common AR-15 platforms and cartridges: .223 Remington, 5.56x45mm NATO, and .300 Blackout—giving you a single magazine design that adapts to your rifle setup.

If you've ever had a magazine failure at a critical moment—or simply tired of replacing plastics that don't age well—a steel DuraMag magazine is a practical upgrade that pays dividends over years of shooting. It's the kind of gear that earns a permanent spot in your range bag, truck, or safe.

Frequently Asked Questions

Will this magazine work with my .300 Blackout rifle?

Yes. The DuraMag SS 30-round magazine is compatible with .300 Blackout, as well as .223 Remington and 5.56x45mm NATO.

Why is steel better than polymer for long-term storage?

Plastic can become molecularly unstable over time, especially when exposed to temperature swings and humidity changes. Steel holds its structural integrity and shape indefinitely, so your magazine will feed and function the same after years in storage as it did new.

What does the orange follower do?

The orange anti-tilt follower keeps rounds stacked straight and aligned in the magazine body, which promotes reliable feeding into the chamber and prevents rounds from binding or tipping.

Is this magazine compatible with standard AR-15 platforms?

Yes. This is a standard 30-round AR-15 magazine that fits any AR-15 lower receiver chambered in .223 Remington, 5.56x45mm NATO, or .300 Blackout.
