Die Free Co DOS BOOT 10PK DISP CARTON

The Die Free Co DOS BOOT is a low-profile base plate upgrade designed for Magpul PMAG GEN M3 AR15 and M4 magazines. If you run PMAGs and want to squeeze more capacity out of each magazine while gaining practical utility, this is a smart add-on. The DOS BOOT adds 2 rounds per magazine—a small but real gain in combat rifle or competition setups—and serves double duty as a monopod rest when you need to steady your rifle on a barricade, barren terrain, or improvised rest during a long-range session.

Made from high-impact injection-molded nylon with a convex shape, the DOS BOOT is designed to be durable and feel secure under actual use. The added grip surface makes magazine changes faster and smoother, especially when you're wearing gloves or working under pressure. This isn't a flashy tactical mod—it's a functional upgrade that works when it matters.

This listing is for a 10-pack display carton, so whether you're outfitting a squad of rifles, restocking a range bag, or running a team through training, you get enough to equip a full loadout without hunting down singles. Compatible only with Magpul PMAG GEN M3 magazines in AR15/M4 format.
