DuraMag AR-15 9mm Magazine 20rd Stainless Steel Black Finish

The DuraMag AR-15 9mm magazine delivers reliable feeding for pistol caliber carbine builds with its corrosion-resistant stainless steel construction. This 20-round magazine features anti-tilt followers and reinforced feed lips for consistent performance across thousands of rounds.

What Makes This Different

Unlike aluminum magazines that can dent and cause feeding issues, this stainless steel construction resists impact damage and maintains dimensional stability under heavy use. The magazine body won't crack at the feed lips like polymer alternatives, while the stainless steel material provides superior corrosion resistance in humid or marine environments. Testing shows these magazines maintain reliable feeding after 10,000+ round counts where standard magazines begin failing.

Key Features

• Stainless steel body construction resists corrosion and impact damage
• Anti-tilt follower prevents double feeds and misfeeds
• Reinforced feed lips maintain proper cartridge presentation
• 20-round capacity optimized for 9mm Luger ammunition
• Black finish reduces glare and provides tactical appearance
• Compatible with standard AR-15 lower receivers and magwells
• Drop-free design ensures quick reloads under stress

Field testing demonstrates consistent feeding across various 9mm loadings from 115-grain FMJ to 147-grain hollow points. The magazine performs reliably in competition shooting where rapid fire strings demand flawless cycling. Law enforcement agencies report zero feeding failures during qualification courses, while competitive shooters appreciate the consistent bolt hold-open function after the last round.
