DuraMag Speed AR-15 30rd .223 Rem/5.56/300 BLK Blue Aluminum Magazine w/ Black Follower

The DuraMag Speed is a 30-round detachable AR-15 rifle magazine built to feed three calibers from a single body: .223 Remington, 5.56x45mm NATO, and 300 Blackout. The body is machined from 6061-T6 aluminum and finished in a blue hardcoat anodize, giving it the rigidity to resist the flex and swelling that plague polymer magazines and a construction rated safe for extended storage while loaded.

DuraMag's signature T-360 coating keeps the feed lips and interior slick for smooth, consistent feeding and easier loading, while the black follower delivers reliable function across all three supported calibers without feed issues. Whether you run a 5.56 duty carbine, a 300 Blackout suppressor host, or a classic .223 Rem range rifle, this single aluminum magazine covers them all - a battle-proven design that has earned its place as a magazine of choice for OEM manufacturers and end users alike.
