DuraMag SS 30-Round AR-15 Magazine .223/5.56/.300 Blackout Black

The DuraMag SS 30-round magazine delivers proven reliability for AR-15 platforms chambered in .223 Remington, 5.56x45mm NATO, and .300 Blackout. This stainless steel magazine body construction provides enhanced durability compared to standard aluminum alternatives while maintaining consistent feeding performance across multiple calibers.

What Makes This Different

Stainless steel construction sets this magazine apart from conventional aluminum designs, offering superior corrosion resistance and structural integrity. The dual-caliber compatibility eliminates the need for separate magazines when switching between .223/5.56 and .300 Blackout loads. Advanced follower geometry ensures reliable feeding with both supersonic and subsonic ammunition types, while the reinforced feed lips maintain proper cartridge presentation under sustained use.
