These extensions are designed for Vudoo Gun Work's .22lr AICS magazines. I use 10 round polymer magazines, and these will not work on the aluminum magazines. In a 10 round magazine you can load 11 rounds with the loading button installed or 12 rounds with the loading button removed. The button can be removed and installed without disassembling the magazine. If you remove the floor plate retainer you can get 13 in, but I have not tested feeding.

Everything except the floor plate is reused. A couple people mentioned they had issues with my original design coming off, so I created this version that uses 2 4-40 set screws to hold the extension in place. This screw size was chosen because it matches the set screw in the Vudoo Gen 2.1 bolt, so I already carry the appropriate Allen key when shooting. Though not strictly necessary, I highly recommend chasing the holes with a 4-40 tap and lightly dimpling the magazine as seen in the pictures above.

They are designed to print without supports. I printed them in PLA and PLA+.
