The Regulator Piston comes as an assembly. DO NOT take this apart. It has a built in blow off valve that will leak air if your marker becomes over pressurized. The blow off resets once your pressure goes back to normal. This safety feature is found exclusively in AGD markers. Replace the entire assembly if your marker is shooting at normal speeds and it still leaks out the back.

He just needs the oring that goes on the outside. They are talking about removeing the internal of the piston. the Oring is ok to replace as long as its bought and made for the reg piston for your piticular valve.
