Hi all!

The last version:

Sorry I think that I haven’t video of shoot, I search :oops: , moreover this spudgun is dismounted to make the next one.

Specifications:
- Ammunition: nail, balls out of glass, roll of the dice of tractor, potatoes,…
- QEV homemade
- Pressure: 13 bar= 188 psi with the extinguisher (or 40 bar= 580 psi with fridge compressor and without the extinguisher) …

great work, a little dead space, but thats for a good purpose.

And where in the world do you obtain all the high pressure fire extinguishers, You must get them used because other wise they would be expensive

Thank for your comment.

For the fire extinguisher my dad was a voluntary fireman, so he can help me for find co2 extinguisher ;) ; but the extinguisher on my spudgun isn’t for high pressure, I’m obliged to shoot without it when I pressurized at 40 bar.

For more autonomy i used this reserve:

For the next i think that I will buy a little paintball tank (20oz,...).

Very nice, I would feel much safer replacing my fire extinguisher tank with a CO2 extinguisher, but I can't get one and I had a couple spare cry chemical ones. Nice gun!

Well made, have you considered having a spring loaded piston valve? This would allow you to eliminate the ball valve at the chamber and still get multiple shots, something like this:

Why not, it's ingenious.

The ball valve was opened just a little to limit the flow.

Or, i could use my hammer valve directly instead of using it as exhaust for my qev, and if i add a loader i would have a semi auto.
