Hello!
My name is Gordan and I live in Zagreb, the capital of Croatia.
I've started making airguns 2 years ago over witch I had a chance to find out how destructive but fun they could be.
Basically what I do is make an air gun out of pvc and put it in a wooden frame(witch I make out of firwood) that has a shape or a real firearm.
I use a spring to open my firing valve, I got a safety valve behind the firing valve, schrader valve to pump the airtank and a bolt on all of my rifles...and they go up to 10 bar. Right now I'm experimenting with piston valves....
You can check out my rifles here:

btw. dont worry, my pvc wont fragment because of high pressure, I use green ekoplastik pvc that has a thick wall and will split rather then fragment if theres an explosion. I'm not sure if they are avalibile only in Croatia...
