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.

Nice set up.And yes that is a pope valve.

You people and putting your blow guns on the side tsk tsk.

Why is the chamber so far from the barrel may I ask?

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.

Nice first build. Hope you enjoy using it.
It should give you a nice break from all that cricket. Laughing

.......(the bat, the telly).

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