The DuraMag AR-15 Speed magazine delivers reliable feeding performance for both 300 Blackout and 5.56/.223 ammunition in a distinctive desert gold finish. This 20-round aluminum magazine features advanced follower geometry and spring tension optimization for consistent function across multiple calibers.
What Makes This Different
Unlike standard AR magazines that require separate units for different calibers, this DuraMag handles both 300 Blackout and 5.56/.223 rounds without modification.
