This instructable is on how to make an airsoft/paintball buzooka.
Step 1: What you need.
what size of pipe you want is completely up to you but I strongly recommend 1.5 size pvc pipe.
what you need.
1 piece of 1.5in, 2 foot long pvc pipe.(make sure your pipe is strong and thick so it doesn't blow up because were using compressed air.
another piece of 1.5in pvc pipe but this time 20 inches long.
a 1.5in end cap.
1.5in pvc ball valve
a bicycle tire valve
and cold weld.
