DuraMag Speed AR-15 30rd .300 Blackout/.223/5.56mm 6061-T6 Aluminum Magazine - Gray w/ Orange Follower

The DuraMag Speed is a 30-round detachable AR-15 magazine built to feed .223 Rem, 5.56x45mm NATO, and 300 Blackout from a single, battle-proven body. The magazine is constructed from premium 6061-T6 aluminum with a gray anodized finish, giving it the rigidity and corrosion resistance that polymer magazines cannot match. Unlike plastic magazines that flex and swell under extended load, the DuraMag Speed holds its dimensions in long-term storage and on the range.

Inside, an orange anti-tilt follower keeps every round aligned for smooth, consistent feeding, while DuraMag's T-360 coating reduces friction for easy loading and reliable function across all three supported calibers. The improved USGI-style geometry makes it a true drop-in replacement for standard STANAG-pattern AR-15 magazines, trusted by OEMs, law enforcement, and military users worldwide.

Whether you run .223 Rem at the range, 5.56 NATO for duty or home defense, or switch to 300 Blackout for suppressed work, this single DuraMag Speed magazine covers all three without compromise. Lightweight, durable, and finished in non-reflective gray with a high-visibility orange follower, it is built to be loaded and left ready.
