Die Free Co Dos Boot +2 PMAG Gen M3 Extension 3-Pack

The Die Free Co Dos Boot replaces the base plate on Magpul PMAG Gen M3 AR-15/M4 magazines and adds 2 rounds of capacity. It fits the 10, 20, 30 and 40 round Gen M3 PMAGs and installs without tools. This pack holds three base plates in black.

DFCO shaped it with 20 round magazines in mind, keeping the profile low so the magazine can work as a monopod in prone without the grip hitting the dirt. The convex bottom rocks smoothly for small position changes, and the aggressive tread gives you a solid hold on reloads. Injection molded impact resistant polymer.
