Description
Fixed version of PP MCX-ish folder. I didnt want to buy springs and hardware that I didnt have to make the folding version, so I made this.
Credit to Philz Phree Phyrearms Phoundation on the sea for the stock footprint!
Based on the legendary MCX thin folding stock.
Stock has a standard male 1913 picatinny rail. I've made a dedicated picatinny coupler for it to put on your AR22 builds, airsoft m4's, or any other picatinny rail system you'd like.
This is modified to have locking lugs on the stock picatinny that accepts m4 hardware.
You will need:
4x M4 x 30 socket head screws
6x M4 nuts
2x m4 x 16 socket head screws.
Orientation of the stock in the 3MF is optimized for strength.
Minimum 8 walls for a decently rugged stock.
Do not over torque the picatinny coupler screws, maybe 15 inch lb.
EDIT 2-21-25
Added a “built-in” female picatinny version to get rid of the need for the picatinny adapter. Separate 3MF uploaded.
