a5 leak

[burtonriderx93x]

when i screw a tank into my a5 it leaks a lot of air out through the barrel its not like a little hising sound its more like if you took your barrel off your gun and blew through it with your more really hard andyone what is causing the leak??

The cup seal is not sealing. Try putting a few drops of marker oil in the ASA, then screw the tank in after you've cocked the gun.

What's probably happening is that the main spring is pushing on the hammer, holding the valve open.
