The bullets are 15mm fishing sinkers covered in duct tape so that the pressure builds up.
The barrel is a smooth 15mm stainless steel pipe.
The loading chamber is a threaded 20mm steel pipe with a threaded cap on top.

A 15x20mm adapter connects the 15mm barrel to the 20mm T fitting.
It has a pressure washer trigger and uses a pressure washer hose connected to a 40kg tank of carbon dioxide.

You will need multiple threaded adapters to connect the trigger to the T fitting and also the hose to the tank. There is many combinations you can choose.

Cute! I like the kick it gives, I guess you can take down an aggressive secret girlfriend dad with that. :twisted: Tell us a little more about how you made it.
Ideas don't make holes. The weapons yes! ;)
