The Die Free Co. DOS Boot 3-Pack (Coyote) is a purpose-driven upgrade for your rifle magazines, delivering enhanced performance, increased capacity, and improved handling in one simple, rugged solution. Designed as a direct replacement baseplate for Magpul PMAG® Gen M3 magazines, the DOS Boot transforms your standard magazine into a more capable and versatile tool.

Each DOS Boot adds +2 rounds of capacity without significantly increasing overall footprint, giving shooters more firepower without compromising reliability. The tool-less, drop-in design ensures quick installation and dependable performance right out of the box.

Beyond capacity, the DOS Boot features a textured, convex profile that enhances grip during reloads and manipulations—especially in adverse conditions or when wearing gloves. Its extended base also functions as a stabilizing monopod, providing improved support and control when shooting from prone or supported positions.

Constructed from impact-resistant polymer, the DOS Boot is built to withstand hard use in training, duty, or field environments. Compatible with a wide range of PMAG sizes—including 10, 20, 30, and 40-round magazines—it offers flexibility across multiple setups.

Sold as a 3-pack in coyote color, this upgrade is ideal for shooters looking to enhance multiple magazines at once with a reliable, low-profile solution.
