x-valve leak ???

[loverboy4604]

hey can someone tell me why my x-valve would leak out the back at the velocity adjustment at all times? it leaks when its up too 300fps or down near 200fps. it only seems not to leak once my air pressure is below 800psi or so.... this is very frustrating because this is an awesome upgrade and i love it but the leak is very frustrating....

thanks Jon shake'n'bake

Sounds like a bad reg piston. It happens from time to time. Mine decided to die in the middle of a game. A quick replacement and you're set to go. Call up AGD and have them send you a new one, especially if it's a new Xvalve.
