Die Free Co Dos Boot +2 PMAG Gen M3 Extension 3-Pack Coyote Brown
The Die Free Co Dos Boot +2 PMAG Gen M3 Extension 3-Pack Coyote Brown is a three-pack of enhanced base plates for compatible Magpul PMAG GEN M3 AR15/M4 magazines. Each Dos Boot replaces the standard base plate, adds two rounds of capacity, creates a convenient magazine monopod surface and adds an aggressive grip area for magazine handling and reloads.
This listing is for the Coyote Brown three-pack, manufacturer part number DOS-BOOT-COYOTE, supplied UPC 860013578138. Die Free Co specifies compatibility with PMAG 10-, 20-, 30- and 40-round GEN M3 magazines. The product is a tool-less, drop-in replacement made in the USA from impact-resistant injection-molded polymer.
Upgrade three compatible magazines in one package. Check magazine generation, local capacity restrictions and the correct color before purchasing the Die Free Co Dos Boot 3-Pack at BattleHawk Armory.
Two Additional Rounds per Compatible Magazine
The Dos Boot adds +2 rounds to each compatible PMAG GEN M3 magazine. Die Free Co originally designed the extension around 20-round magazines, where two additional rounds represent a 10-percent capacity increase. The same base plate is also specified for compatible 10-, 30- and 40-round GEN M3 PMAGs.
Magazine capacity can be regulated by state and local law. Customers are responsible for confirming that purchasing, installing and using a capacity-increasing component is lawful in their jurisdiction. BattleHawk Armory should apply its current shipping and sales restrictions before making the listing available.
Magazine Monopod and Prone Support
The Dos Boot's extended, convex base gives the magazine a broader contact point for prone use. Die Free Co describes this as converting a compatible PMAG into a convenient monopod. The design began with the goal of keeping the user low to the ground without allowing the rifle grip to contact dirt, while still permitting smooth positional adjustments.
The convex shape is intended to move more naturally during small position changes than a flat, sharp-edged base. The aggressive tread improves contact with the ground and also creates a more pronounced surface for grasping the magazine during removal or reloads.
Tool-Less Drop-In Installation
Each Dos Boot is designed as a tool-less, drop-in replacement for the original compatible base plate. Before installation, unload the magazine completely and follow the current Die Free Co and Magpul instructions. Control the magazine spring and locking components during disassembly, confirm correct reassembly, and function-check the magazine before relying on it.
The manufacturer specifies PMAG GEN M3 compatibility. Do not assume that a similarly shaped earlier-generation magazine, a non-Magpul magazine or a different caliber magazine uses the same base-plate interface.
Coyote Brown 3-Pack
Coyote Brown provides an earth-tone contrast on black magazines and coordinates with Coyote or FDE equipment. The manufacturer-hosted image supplied for this variant shows the Coyote Brown extension installed on a compatible PMAG.
The package contains three Dos Boot extensions, allowing three compatible magazines to be configured alike. Magazines are not included unless the BattleHawk Armory product page explicitly states otherwise.

Impact-Resistant Polymer and Handling Texture
Die Free Co uses impact-resistant injection-molded polymer for the Dos Boot. The aggressive tread is intended to provide solid contact when used as a support surface, while the improved grip area can make the magazine easier to grasp. These features add utility without requiring tools or permanent modification to the compatible magazine body.
