ProMag DRMA1-FDE 50-Rd .308 Drum Magazine AR-10 FDE Polymer

The ProMag DRMA1-FDE is a high-capacity 50-round drum magazine built specifically for AR-10 pattern rifles chambered in .308 Winchester / 7.62x51mm NATO. It drops into the standard magazine well of LR-308 (DPMS) and SR-25 pattern platforms, giving .308 AR-platform shooters a much higher round count on tap without frequent reloads.

The drum body is molded from durable polymer in a Flat Dark Earth finish that keeps weight down while resisting impact and the elements. Inside, a steel-reinforced feed system supports consistent round delivery into the chamber. The magazine installs and removes as a standard detachable unit and measures roughly 12.7" long by 4.6" tall.

Whether you are burning through rounds at the range, running drills, or simply want fewer reloads, the DRMA1-FDE brings genuine 50-round capacity to your AR-10. Like all ProMag products, it is backed by a lifetime warranty.
