Simple Airsoft Picatinny Folding Brace

Simple Folding Brace V2

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

It locks in place when unfolded, and with a simple press of a button, the brace 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.)

Two hinge versions are included:

• Standard: For most rear Picatinny rail adapters.
• XS: A shorter hinge for a more compact setup.

----- Assembly -----

To assemble the folding brace, 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.
