Hi everybody :)
I saw this gun here, [/url]http://www.spudfiles.com/forums/adjustable-bbmg-t22834.html[url]. and I really liked it, simple and really powerful relatively to the pressure he was using :shock: and the accuracy is very reasonable :roll: .
As I have a fridge compressor and a paintball tank with a regulator, I see no reason to not to try build one for my self. So today I use a blowgun, a o-ring detente(made from a push to connect hydraulic fitting), the air tank and I took it to make some shots. The bottle with charged to 40 bar, regulate to 150 psi. The power was great, but the accuracy and consistency are really bad :( . The poor accuracy was because I didn´t make a barrel for it yet, but the consistency I don´t know much :roll: any ideas?

Damages? well there was a LOT as the o-ring detente only works at 200 psi :shock: but somebody thrawed all the targets away before I took any pictures. And this thing is to dangerous for me to use my video camera.
stock made with polystyrene covered with epoxy :shock:
As the o-ring detente was too strong, I´m going to try a non air tight spring detente
