Hi everyone!
Long time reader first time poster. Just thought I would show you all the air rifle I have been working on. Body is all brass water pipe and fittings I got from bunnings. I did have a brass sprinkler valve on it but it was very unreliable, so replaced it with a regular plastic one(un-modded). Main tank is a converted 9L lpg bottle.
Turn the yellow valve on the bottom to prime a shot. Trigger is an ordinary light switch.

That thing looks super ghetto!! How is the performance?? You should mod the sprinkler valve, takes 5 minutes!!

Nice first pnuematic, all those brass fittings must be heavy though?

Yea, weighs roughly 8 or 9 kg. But being a carpenter I like the weight:)
