DuraMag Speed 30rd AR-15 Magazine 223/5.56/.300 BLK Bronze

The DuraMag Speed 30-round magazine delivers enhanced feeding reliability for AR-15 platforms chambered in 223 Remington, 5.56x45mm NATO, and 300 Blackout. This aluminum-bodied magazine features an anti-tilt follower design that reduces feeding malfunctions during rapid fire sequences.

What Makes This Different

Unlike polymer magazines that can crack under stress, the DuraMag Speed uses 6061-T6 aluminum construction with a hard-coat anodized bronze finish. The magazine body maintains dimensional stability across temperature extremes from -40°F to 180°F. The black anti-tilt follower incorporates four bearing surfaces that prevent binding during the feeding cycle, addressing common failure points found in standard GI magazines.

Key Features

• 30-round capacity compatible with 223 Rem, 5.56 NATO, and 300 Blackout cartridges
• 6061-T6 aluminum body with hard-coat anodized bronze finish
• Anti-tilt black follower with four-point contact design
• Stainless steel spring rated for over 10,000 compression cycles
• STANAG 4179 compatible with AR-15/M4 pattern rifles
• Self-lubricating follower coating reduces friction
• Detachable floorplate for maintenance access

Field testing demonstrates consistent feeding across multiple ammunition weights from 55-grain FMJ to 77-grain match bullets. The magazine functions reliably in competitive shooting environments where rapid magazine changes are critical. The aluminum construction resists impact damage better than polymer alternatives while maintaining the lightweight profile essential for tactical applications.
