32mm scope to picatinny rail adapter

thingiverse

If you bought a Chinese-made 32mm air rifle scope and want to attach it to a Picatinny rail, you'll need the top halves of the original scope mounts along with three M4 nuts and three 25mm-long countersunk machine screws for each mount. Typically, you'll need two sets. Print the main mount on its side and the clamp part with the V-groove facing downwards. Insert the nuts into the hexagonal slots and screw everything together securely.
