What all parts on a Surgeon 591 should or need to have Robars NP3 finish applied? Surgeon 591 receivers are chrome molly and the bolt has Ion Nitride (Case Hardening)so need to have a protective coating but I dont know what all I should have coated. Should all the components such as the firing pin,all springs,ejector, extractor,retaining pins,etc. be done or just certain parts?
Any info would be Greatly Appreciated.
