This is my FIRST pneumatic gun it works pretty good but i havnt got any damage pics yet. The sprinkler valve used to leak but i some how stopped it i just dunno how.

The chamber is 40X500mm.
The sprinkler valve is 1 inch modded pope valve i think.
The stock is made from 20mm pvc and is blocked off at the T. (with $1 coins)

My first pneumatic so suggestions welcome.

I seperated the barrel and the chamber that far so that the trigger would fit in where it is. And also i didn't know that that made a diference in peformance.

Would I be right in thinking the blowgun is off a sprayer?
