I bought surplus K31 with Walnut. Yesterday took bolt out, cleaned very well all parts, cleaned barrel.
There was cosmoline(or grease?) on barrel and bolt. I know how to deal with barrel, it's clean now. But what do I do with bolt? Should I lubricate it somehow? How much? Regular oil or I need to use some kind of grease?
Thank you!
