Die Free Co Dos Boot +2 Magazine Extension Magpul PMAG Gen M3 AR-15/M4 Black 3-Pack

The Die Free Co Dos Boot +2 is a low-profile magazine base plate upgrade engineered specifically for Magpul PMAG GEN M3 AR-15/M4 magazines. Sold as a 3-pack in matte black, the Dos Boot adds +2 rounds of capacity to compatible 10-, 20-, 30-, and 40-round PMAGs while doubling as a functional monopod for added shooting stability and improving grip geometry for faster, smoother reloads.

Molded from high-impact injection-molded polymer, the Dos Boot is fully ambidextrous and installs tool-free in seconds with no modifications required. The low-profile design preserves the original magazine footprint while extending the base for better purchase during magazine changes. Each pack includes three Dos Boot extensions and is compatible with Magpul PMAG GEN M3 10-, 20-, 30-, and 40-round AR-15/M4 magazines.
