DFCO Dos Boot (3-Pack) – Black Magazine Extension
The Dos Boot by DFCO is an enhanced base plate upgrade for Magpul PMAG GEN M3 AR15/M4 magazines. This extension adds 2 rounds of capacity, converts the magazine into a convenient monopod, and improves grip for quicker, smoother reloads.
Originally designed for 20-round magazines, the Dos Boot stays as low to the ground as possible without letting the rifle grip touch the dirt in prone positions. It provides roughly a 10 percent capacity increase, improved ground stability, and easier handling thanks to its contoured shape and aggressive tread.
Although optimized for 20-round magazines, the Dos Boot also fits Magpul GEN M3 magazines in 10-, 30- and 40-round configurations.
