Need suggestions for removing rust from inside action. I have been cleaning some guns for a sister in law. These were her husbands and were put away several years ago with no care. Safety on this 311 was broken off so I removed the stock to see how hard it would be to replace. This thing must have spent many wet days out as the inside is full of rust. Surprisingly he must have wiped the outside down as it doesn’t look bad. I have been soaking it in diesel then using brushes and picks to work inside but it still is frozen up. Would it hurt to use something like Evaporust to try and get the rust out and free up the parts or do I just have to keep soaking and get some disassembly instructions and clean the parts up when I get it apart?
Thanks for any ideas.
