DuraMag AR-15 30rd Magazine 300 Blackout 5.56 OD Green Aluminum

The DuraMag Speed 30-round magazine delivers enhanced feeding reliability for AR-15 platforms chambered in 300 Blackout and 5.56/.223 calibers. This aluminum construction magazine addresses common feeding issues found in standard GI magazines through precision engineering and advanced follower design.

What Makes This Different

The DuraMag Speed incorporates a four-way anti-tilt follower that maintains consistent cartridge presentation throughout the feeding cycle. Unlike standard aluminum magazines that rely on basic followers, this design reduces double-feeds and failure-to-feed malfunctions by 40% in testing. The stainless steel spring maintains tension longer than traditional carbon steel alternatives, ensuring reliable function even after extended storage periods loaded to capacity.

Key Features

• Four-way anti-tilt follower prevents cartridge binding and misfeeds
• 6061-T6 aluminum body with Type III hard anodizing in OD Green finish
• Stainless steel spring rated for 10,000+ compression cycles

Field testing demonstrates consistent feeding across temperature ranges from -20°F to 140°F without lubrication adjustments. The magazine functions reliably in both semi-automatic and full-auto applications, making it suitable for competition shooting, tactical training, and duty use. The hard anodized finish resists corrosion in marine environments and maintains dimensional stability under repeated loading cycles.
