Popgun pete, thank you for the explanation and the great diagram, you helped me a lotThat is the older type one-way valve in the power regulator bulkhead and goes in from its rear face. The valve and the rubber seat are combined in that little solid rubber cylinder. When pressure is greater in the gun’s pre-chamber, i.e. the upper handle volume, it is blown forwards against its spring and opening up to let air flow forward into the tank, but when pressure is greater in the tank than the rear prechamber it shuts off air attempting to flow rearwards from the tank.

I am just looking at your gun to see which model it is.

Your gun is just before the version shown at post #10, so should use the same parts, the numbers are shown in that red box. How we can tell is Mares initially had a butt plate with a metal post on the handle, then they kept the butt plate but moulded an eyelet to tie a cord to the grip. The next thing was to eliminate the butt plate and mould a short tab to provide the eyelet. That means the grip handle floods on all guns since then. The "O" ring is part number 5537.
