ERRR..Valve Leak

[PBCapo]

I lent out my backup mag, and now theres a leak out of the back of the valve, where you adjust the velocity, who knows what to do?

velocity adjuster is in the back of the valve(its right in the middle you cant miss it) you can adjust it with a 1/8th allen wrench

wow, o know that, its leaking out of the whole in the velocity adjuster though

[ß?µ£ §mµ®ƒ]

oh try oiling your gun first try that then tell us whats up

Either your velocity is up too high, or your regulator piston needs replacing. You can try replacing the oring on the reg piston first. Let me know if this works.;)

What he said.
Try turning the nut in the back of the gun out some. See if that stops the leak. If it doesn't then you could have a really messed up reg seat, a bad piston o-ring, or or possibly a bad piston-spring pack.

i have the same problem, i tried everything from replacing piston o-rings to oiling the whole thing it still leaks ...
i only can shoot 260 fps max any higher than that it leaks bbadly ... i also notice that theres a metal washer between tthe spring back and the velocity adjuster. isnt it supose tto be an o-ring not a metal washer? ...

He probably thought that he would turn up the velocity, and when it started leaking thought he broke it and stopped using it. Turn the nut counterclockwise a bit and see if that helps.
