Does anyone have the correct list of "O" rings for the liberty ? Looking at the schematics I think changing "O" rings in the gun should be pretty easy and no where near as difficult as many USA made guns. Who here has taken this gun apart ?The one big advantage to PCP guns is when they fail it is very, very most likely a "O" ring problem, maybe a poppet problem, but mostly "O" ring. This sort of insures the gun itself can be useful for many, many years of use.Thanks in advance guys.wll
