Custom Airsoft Picatinny Folding Stock V2

Custom Folding Stock V2

This is my new and improved folding stock design for airsoft replicas with a rear Picatinny rail.

Compared to my previous version, this one is simpler: less hardware, no glue, and a slimmer overall design while still being solid and reliable. 

This will now be my standard base for future folding stock designs.

It locks in place when unfolded, and with a simple press of a button, the stock folds and snaps into place to keep it from flopping around. (Note that it may unsnap if moved too hard, as it’s a simple snap-fit mechanism.)

Available in 3 lengths:

-22 cm

-24.5 cm

-27 cm

----- Assembly -----

To assemble the folding stock, you'll need:

-1 × 7x12mm compression spring (for the button, available on MakerWorld)

-1 × M3 × 16mm screw (to hold the button in the stock)

-2 × M4 × 30mm screws + nuts (to clamp onto the Picatinny rail)

-1 small piece of filament (used as a hinge pin, melted on both ends to hold it in place)

Melt both ends of the piece of filament to lock the pin in place:

Some light sanding may be needed on supported areas for a clean fit.
