by airstopper do you mean blow gun/ hose gun/ pilot valve?
maybe the qev is the wrong way around?

A picture of your piston would be helpful, is it a tight fit in the tee?

Probably what is happening is that more air can flow past the piston than can flow out of your "airstopper"

i mean the part, that make the gun semi auto! at the end of the grip
you can see it on 1.55
how do i made this?
when i load my gun, it doesn't work because the piston of the qev won't open, it has not enough air to blowback the piston..
i mean when i have mount this "part that makes it semi auto.."airstopper"
do ya understand?
