The Die Free Co Dos Boot +2 magazine extension is a purpose-built baseplate upgrade designed to add capacity and functionality to your Magpul PMAG Gen M3 magazines. This three-pack of Coyote Brown extensions transforms your standard AR-15 mags into more capable platforms—adding two rounds per magazine while doubling as a monopod for prone stability and offering a better grip surface for faster, smoother reloads. It's the kind of no-nonsense gear upgrade that works as hard as you do.
Die Free Co engineered the Dos Boot with 20-round magazines in mind, sizing it to keep your rifle's lower receiver clear of dirt when shooting prone. The result is a low-profile extension with genuine utility: the aggressive tread pattern locks against your shooting surface, the contoured shape facilitates smooth transitions between positions, and the textured grip makes mag changes more confident under stress. Tool-free installation means you drop it in place and forget about it—no gunsmithing required.
While optimized for 20-rounders, the Dos Boot plays well across the PMAG Gen M3 lineup, fitting 10, 30, and 40-round variants without compromise. Each extension is molded from impact-resistant polymer, built to handle the realities of field use, and made here in the USA. Whether you're running a precision rifle build, setting up a duty carbine, or just looking to squeeze more utility from your existing magazines, this is a straightforward upgrade that does exactly what it promises.
