yeah there is an airline behind his wrist but that is obvious.....a slide valve normally lets air and it goes throught the pilot side to the chamber.... then when he opens the valve it vents air from the pilot side and when he closes the valve it starts filling the chamber again...

Hmm I was considering using a slide valve becasue it only vents the pilot side but if it requires more force to open as the pressure increases then this thing sucks....

BTW. I am totally drunk anyone else here is drunk :D ?

Hey Poland, just for us dummies out there how is it obvious that he has a air line behind his wrist? I watched the vid a couple of times and couldn't spot it.
Do you mean it is obvious because of the performance? I would tend to agree.

eeeekkhmmm becase he has to fill it with air somehow..... :?

in other words.... his chamber would have to hold at least 1000 psi. to fire those several shots.... i can't see any other principle it could operate on....... and this configuration (an airline and a slide valve seems to be the most obvious)

keep in mind that this chamber is really small and the barrel has very large diameter( = large volume of air)

No, a slide valve doesn't need significantly more force as the pressure increases. There might be a small increase due to more pressure causing more o-ring friction, but I doubt it would even be noticeable.

As for the gun I would agree with the others, air line behind his wrist and a simple slide valve and QEV setup.

well you can hear a sound in the background that sounds like a compressor but at the end of the video he lifts his hand up and in the tiny bit of space i cant see any hose i think someone should just try it and find out

In another vid of his you can hear air leaking constantly in the background and sounds of possible chamber refill
