DFCO DOS BOOT™ 3-PACK +2RND BASEPLATE FOR MAGPUL PMAG GEN M3 (10/20/30/40) – BLACK / COYOTE

Thought the world’s most reliable polymer magazine couldn’t get better? Think again.

The Dos Boot™ by Die Free Co (DFCO™) is a purpose-built baseplate upgrade for Magpul PMAG GEN M3 magazines that adds +2 rounds, improves handling, and turns your PMAG into a stable monopod-ready support for prone and barricade work—without the bulk or snag hazards of oversized “mag pods.”

DFCO designed the Dos Boot around a simple mission: get lower, stay stable, and reload faster. It was originally tuned for 20-round PMAGs, giving you the lowest practical profile while keeping your rifle’s grip off the dirt. The final shape delivers a smooth, convex contact surface that lets you depress or elevate the muzzle without being stuck on a hard edge—so you can make small corrections and track targets cleanly.

Even though it was born on 20s, the Dos Boot fits right in on 10, 30, and 40-round GEN M3 PMAGs too. That means you get the same upgraded control and stability across your whole loadout.
