ProMag DPMA4FDE 40rd .380 ACP AR-308/LR-308 Magazine Flat Dark Earth

The ProMag DPMA4FDE delivers extended capacity for AR-308/LR-308 platforms chambered in .380 ACP, providing 40 rounds of reliable feeding in a durable polymer construction. This magazine addresses the need for higher round counts in training scenarios and competitive shooting applications where frequent reloading interrupts performance.

What Makes This Different

Unlike standard capacity magazines that limit shooting sessions, the DPMA4FDE extends range time with its 40-round capacity while maintaining the lightweight characteristics of polymer construction. The Flat Dark Earth finish provides enhanced corrosion resistance compared to standard black polymer, particularly in humid or coastal environments. ProMag's spring-loaded follower system ensures consistent feeding across the full capacity range, reducing the feed issues common in extended magazines.

Key Features

• 40-round capacity reduces reload frequency during extended shooting sessions
• Flat Dark Earth polymer construction resists impact damage and environmental wear
• Compatible with AR-308/LR-308 pattern rifles chambered in .380 ACP
• Spring-loaded follower maintains consistent cartridge presentation
• Reinforced feed lips prevent deformation under loaded pressure
• Anti-tilt follower design reduces jamming and misfeeds
• Easy-load design accommodates rapid magazine filling

Field testing demonstrates reliable cycling through the full 40-round capacity in both semi-automatic and rapid-fire applications. The magazine functions effectively in competition environments where high round counts are standard, as well as training scenarios requiring sustained fire capability. The polymer construction maintains dimensional stability across temperature ranges from -20°F to 140°F, ensuring consistent performance in varied conditions.
