what prevents a tank with a on/off valve from shooting off like a rocket if for some reason the vavle is open? is the orfice not large enough to let enough pressure out? This question has been buggin me, i dont know why, lol.

If i am not mistaken the pin still has to be depressed to get the gas out. The on/off is on the other side of the pin.

actually . if you look at a smartparts on off for a co2 tank .. it can be turned on with air just flowing the crap out of it ...

But on all HPA tanks you do need to depress the pin
