Mission First Tactical EXDPM556WBL 30rd AR-15 Magazine 5.56/.223

The Mission First Tactical EXDPM556WBL Extreme Duty magazine delivers enhanced reliability for AR-15 and M4 platforms through advanced polymer construction and precision engineering. This 30-round magazine addresses common feeding issues that plague standard magazines during extended use.

What Makes This Different

The Extreme Duty series incorporates a reinforced polymer body with enhanced feed lip geometry that maintains consistent cartridge presentation under stress. Unlike standard GI magazines that can develop feed lip spread over time, the EXDPM556WBL maintains structural integrity through thousands of loading cycles. The magazine features an improved follower design with anti-tilt properties that prevents double-feeds and bolt-over-base malfunctions.

Key Features

• 30-round capacity for 5.56x45mm NATO and .223 Remington cartridges
• Reinforced polymer construction resists impact damage and temperature extremes
• Enhanced feed lip geometry prevents cartridge rim damage during extraction

Field testing demonstrates consistent feeding across various ammunition weights from 55-grain FMJ to 77-grain match loads. The magazine performs reliably in temperature ranges from -40°F to 180°F, maintaining spring tension and follower function. Law enforcement agencies report improved reliability during qualification courses and extended training sessions compared to aluminum alternatives.
