Park everything that is metal that needs it. many times the rear sights don't need to be re-parked etc. Any part you wish to protect that the moly or gunkote will not be able to reach. Inside the receiver , trunnions etc. Good luck ! Jerod
I think the piston is stainless steel and it won't park.mr. wipple said:Is it O.K. to park the bolt? Disassemble the bolt of course. Will the gas piston need to be removed to prevent being parked? I can only assume the piston is chromed and won't park.
