Just inherited my grandpas Marlin 30-30. It's got some rust on the barrel and I am unsure how long it has been since the last cleaning. I want to strip it and do a deep clean, but I don't know how to take it apart completely. I know how to take the lever, bolt and ejection pin out, but I have no clue on how to do the rest. I am also looking for suggestions on what products to use.
