I just shoot it down or connect fill hose crack the tank open a little till you hear the click then shut it tight then SLOWLY! crack that bleeder then STOP! let it SLOWLY! piss out all the through the bleeder or you can also carefully loosen the manometer a little.
Yes, DO NOT shoot it down... With guns without a dedicated bleeder best way is usually the pressure gauge or the fill foster. Just slightly loosen either until air escapes then slowly bleed it down...
Thanks for the input. This one doesn't have a foster. It uses a plug like the wildcat. I could remove the hammer and press on the end of the valve I guess. Sounds dangerous though. Maybe the gauge is the best way to go.
