Airsoft USW Kit

A 3d printed USW kit that fits most airsoft glocks. Tested to work with EF G18 and WE G19. I primarily use the EF G18 in this kit, as such I included a slim fire selector.

No brass inserts are needed but some screws are required, including:
M5 Nut x5 (Body and Stock Mount)
M5x40mm x1 (Screw Grip and Body)
M5x35mm x4 (Stock Mount and Handle)
M5x30mm x1 (Stock Hinge)
M5x15mm x1 (Handle Nub)
M5x8mm x2 (Optics Rail)
M3x30mm (Stock Lock)
7x10mm spring (Stock Lock)

This is WIP and as such there are some issues to note when building the kit.
The glock may fit a bit loose in the body, and adding some duct tape to the tail of the glock makes for a snug fit.
The stock may be loose in the retracted position and unlatches when firing, but can be improved by tightening the hinge. You can also apply some heat to the latch on the body and fold the stock. This allows the latch to conform to the shape of the catch on the stock and improves retention.
