Here's my gun, it's made from poly pipe threaded fittings with a 1.25L soda bottle as the chamber. It has a 3/4 inch ballvalve (might upgrade to a sprinkler valve) and I use it at 80 psi (every bottle I use I test to 100psi) It can send an AA battery out of sight straight up The bottle's lid was sanded and epoxied into the reducer. (so the bottles can be replaced)

This is my only real gun other than a few minis.

EDIT: Oh and the picture quality is so bad because I'm hosting this on spudfiles, and not on photobucet or somwhere like that.

I wonder how much deeper the ocean would be without sponges.
Right now I'm having amnesia and deja vu at the same time. I think I've forgotten this before.

He means how did you get the bottle to thread into the pipe or am I wrong.

I drilled a hole in the lid of the sprite bottle, then epoxied it into the fitting.

You should be able to take it a bit higher than 120 psi.

Yeah, but I really don't want it to burst. It works fine with 80, and if I want it to be more powerfull I'll just upgrade the valve.
