AR-15 PMAG GEN M3 Magazine Extension – DOS Boot +2 Round – 3 Pack


PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.

The Die Free Co DOS Boot is a +2 Round magazine extension and enhanced base plate upgrade for Magpul PMAG GEN M3 AR-15/M4 magazines. This 3-pack is built for setting up multiple compatible PMAGs with the same added capacity, improved grip surface, and prone-position monopod support.

Available options are organized below under Variants. Choose Black or Coyote.


Fitment

  • Fits Magpul PMAG GEN M3 AR-15/M4 magazines.
  • Fits PMAG GEN M3 10, 20, 30, and 40 Round magazines when verified by product listing.
  • Adds +2 rounds of capacity per compatible magazine.

Does NOT fit

  • Not verified for PMAG GEN M2 magazines.
  • Not verified for non-Magpul AR magazines.
  • Not a complete magazine.

What it does

The DOS Boot replaces the compatible PMAG base plate, adds two rounds of capacity, improves the gripping surface during reloads, and can serve as a small monopod when shooting prone.


Why it’s worth it

This is useful for AR range setups, training mags, and rifle builds where compatible PMAGs are already part of the system. The 3-pack makes sense when you want multiple magazines set up the same way instead of one lonely upgraded mag acting like it owns the place.
