Product Info for DFCO Dos Boot AR15/M4 2 Round Magazine Extension

Introducing the Dos Boot by DFCO - an enhanced base plate upgrade for your Magpul PMAG GEN M3 AR15/M4 magazines. The Dos Boot adds +2 rounds of capacity, converts your PMAG into a convenient monopod, and improves grip for quicker, smoother reloads. It's the unintrusive and practical magazine upgrade you deserve.image

We designed the Dos Boot with 20-round mags in mind, aiming to get as low to the ground as possible without letting your rifle grip touch dirt. The result? A sleek extension that gives you a 10% capacity bump, better stability in prone, and easier mag handling thanks to its contoured shape and aggressive tread.

Though originally designed for 20-rounders, the Dos Boot is right at home on 10, 30, and even 40-round magazines. It's versatile, practical, and just the right amount of extra.
