Yeah did you know that theair in a full scuba tank can fill a telephone both there is however many litres of air like 120 in one of those iff I am correct which I am about the telehone both thing.

it is easy to modify the qev so that you can have a fill conection in the chamber instead of the qev.

maybe he used somthing similar to JSR s reciprocating piston but didn't have the pop off safety valve pop off automaticly and pulled it manually that would get rid of the problem of it going down to a certain pressure that the auto-matic pop off wouldn't pop off you never know he might have seen it on here and modify it.

QEVs can withstand pressures above 400 psi without any problems...

To get so many shots out of a tiny chamber, there has to be a pretty high pressure in that tube.
The last time that video was posted I think most people came to the conclusion that there is an air line behind his arm that is recharging the gun for each shot. That's the way it seems to me as well.

Then you would see a hose coming out of the top of the chamber, check the design, the fill valve is at the top.

I'm pretty sure the top one is a pop off safety valve and the one at the back is some kind of manual pressure release valve that is conected to a quick release that could be hooked up to a hose.

@Grumpy: Yes - I do, but they're more commonly called sleeve valves in industry. Slide valve is the name they're given by paintballers.
For anyone that wants to achieve semi-auto or rapid fire with a pilot filled valve, they are a godsend. I use one on HEAL, but I had to add my own check valve:
Red thing in the middle with a jubilee/hose clip around it to act as a trigger
I originally picked up mine at Airlines Pneumatics UK here:
http://www.airlines-pneumatics.co.uk/we ... de=S070104
But for those in the US, McMaster-Carr has them. Search for cat number 4622K33, cat page 447 (same page as their air tank Schrader valves by coincidence)
Make sure you get the air variant, the Water/Oil/Gas variants won't vent to atmosphere.
