Although it's definitely leaking, too, just don't know where, and haven't taken the time to check all the possibilities. I'm still getting blow-by at the front of the trigger guard when shooting it, which I seem to recall someone attributed to NO transfer port seal. Still trying to come up with a way to fix that, but so far, no brilliant solution has come to me
. I think I need to tear it down to just the receiver, valve, air tube and cap, charge it up and dunk it in the bath tub. Probably better to fill it with air, then I don't need the hammer to pierce cartridges. Guess it's time to order a Foster fitting for the bulk fill valve. Later.
