DFCO DOS BOOT +2 3PK BLACK

Description

The Die Free Co Dos Boot is a baseplate replacement for Magpul PMAG GEN M3 AR-15/M4 magazines, sold here as a three-pack in black. The core purpose is straightforward: the extended baseplate adds two rounds of capacity to whichever GEN M3 PMAG you’re running, whether that’s the 10-, 20-, 30-, or 40-round version, without requiring any tools or permanent modification. Installation is a drop-in swap using the same retention system as the factory baseplate.

Beyond capacity, the design addresses two practical problems at the range and in the field. The bottom surface carries an aggressive tread pattern that gives your support hand more purchase during a reload — useful when your hands are cold, gloved, or under stress. That same surface doubles as a monopod contact point when shooting from a prone position, letting the magazine take weight off the rifle and providing a stable rest without adding dedicated hardware to your setup. Primary Arms notes the convex profile of the boot is what makes positional adjustment smooth when used this way, rather than a flat surface that tends to catch.

Construction is impact-resistant injection-molded polymer throughout. The Dos Boot is made in the USA. At three per pack, it covers a standard loadout of magazines in a single purchase, and the black finish matches factory Magpul PMAG coloring directly.
