The DuraMag Speed AR-15 magazine delivers reliable feeding performance for 300 Blackout, 223 Remington, and 5.56 NATO cartridges. This 20-round aluminum magazine features an anti-tilt follower system and enhanced feed geometry for consistent cycling across multiple calibers.
What Makes This Different
Unlike standard GI magazines, the DuraMag Speed incorporates a modified follower design that reduces bolt-over-base malfunctions by 40% compared to conventional aluminum magazines. The precision-formed aluminum body maintains dimensional stability under stress while the proprietary spring system delivers consistent tension throughout the full capacity range. Advanced feed lip geometry accommodates the varying case dimensions between 300 Blackout and 5.56 NATO without compromising reliability.Key Features
