X valve leaking out top whole

[Auto_Rook]

Yep, when i gas it up it will do it and when i even shoot it still does it, what do i do. i have ult, x valve, everything. and my tank is putting out preset 850 pmi

Sounds like a bad piston o-ring.

is that the oring when i take the x valve in half theres a little o ring sitting on top of the copper thingy

[Auto_Rook]

ok i fixed it by putting in that new o ring and turning down my velocity. hahaha it was at 320 because i took my velocity thingy out to pack grease in and didnt adjust it back.. AND where can u buy a new velocity back thing for the x valve.. mine i think is stripped the fps place there... oops

No, it's the oring that you sits in front of the regulator piston http://store.airgun.com/index.cfm?fu...&categoryID=23

You change the oring by screwing out the velocity adjuster and drop out the springs and piston.
