Hello. Purchased at an auction a L579 Foester in .308. When I finally received it in the mail I removed the bolt to find that it looks to have been damaged due to rust. The rust has been removed, but the pitting is still obvious. The chamber does not appear to have any sort of damage in the way of rust or pitting like the bolt has. My question is is the bolt safe to use in this condition? How is it possible that there does not seem to be any other sign of neglect ? Is it repairable or should I just replace it ( if possible) with another bolt. The s/n's match gun to bolt so I would like to keep original if possible. Sorry about the pics, but could not get my camera to focus up close. Any and all help would be great!
