Used decent shape CA adapter for PGP and other sheridans, was on a KP2. This was removed from a KP2. I will need new orings. It works by sealing the vent hole and pressurizing the lower chamber. See photo for details. If your vent hole is in a different spot on a different marker I would recommend not buying. Vent hole on pictured body is 3 inches back from end of threads.
