The Dos Boot solves two problems at once: adding capacity without bulk and providing a solid contact point when shooting from prone. It's built from impact-resistant polymer and drops in as a replacement baseplate without requiring any tools. Works perfectly on 20-round mags but fits 10, 30, and 40-round PMAGs just fine.
Die Free Co engineered this with 20-round magazines in mind, keeping the profile low enough that your rifle grip stays off the dirt in prone positions. The contoured shape and aggressive tread surface do double duty: they give you a confident grip for faster reloads and create a stable monopod-style platform when you need it. That textured tread means better traction on gravel, concrete, or whatever surface you're shooting on.
It's truly a drop-in replacement. Pop off your factory baseplate and slide this on. No springs to fiddle with, no tools needed. The construction holds up to real-world use too, which means durability matters here. Impact-resistant polymer means it'll survive drops and rough handling without compromising function.
The +2 capacity bump gives you a practical increase without changing how the magazine sits in your mag pouches or your rifle's overall footprint. Made in the USA, this baseplate extension blends function with straightforward design.
It's simple. Just remove your factory baseplate and drop the Dos Boot on as a replacement. No tools required and takes seconds to complete. The extension uses the existing magazine spring and follower, so no modifications needed.
It was designed with 20-round mags in mind for ground clearance, but works great on 10, 30, and 40-round PMAGs too. The low profile is its strength, especially on 20-rounders where you get that solid monopod feel in prone.
No. The Dos Boot is engineered to work seamlessly with PMAG GEN M3 magazines and maintains full feeding reliability across all compatible capacities. The extension doesn't interfere with internal components.
It does more than add rounds. The aggressive tread and contoured shape give you better grip for faster reloads and act as a functional monopod for prone shooting stability. You get a practical upgrade that actually improves handling, not just capacity.
