ProMag DPMA4FDE .308/7.62x51mm NATO 40rd Flat Dark Earth Polymer Magazine - AR-308/LR-308

The ProMag DPMA4FDE is a high-capacity 40-round detachable polymer magazine built for .308 Winchester / 7.62x51mm NATO AR-pattern rifles. Designed around the popular AR-308 / LR-308 platform, it is also compatible with SR-25 pattern rifles and DPMS-spec AR-10 builds, giving long-gun shooters a reliable extended-capacity option.

The magazine body is injection molded from a proprietary DuPont Zytel-based polymer for light weight and impact resistance, and is finished in Flat Dark Earth to match modern flat-sprayed rifle furniture. Internally, the magazine uses an injection-molded follower and a magazine spring for smooth, consistent feeding.

Whether running a precision AR-308, a hunting AR-10, or a defensive carbine in .308, the DPMA4FDE delivers extended firepower in a durable, lightweight package.
