metal pipe gun

[Exclaim4]

The bullets are 15 millimeter fishing sinkers covered in duct tape. The tape makes the pressure build up when the bullet tries to enter the barrel which makes the bullet violently pop out.

The barrel is a 15 millimeter stainless steel pipe.
The loading chamber is a threaded 20 millimeter steel pipe with a threaded cap on top.

A 15x20mm adapter connects the 15mm pipe to the 20mm T fitting.
It has a pressure washer trigger and uses a pressure washer hose connected to a 40 kilogram 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.
