When I took apart my Ruger 10/22 Takedown that I showed in the last post, and looked at the internals, not only were they filthy, the bolt and receiver was not polished and had a very rough metal finish.
So I took my polishing stone to the bolt, firing pin and receiver to make them shiny and smooth. Seen here, the bolt on an india stone.
forgot to take pics of the polished receiver but here are the bolt and firing pin.
Should make the action much smoother now.
