Personally I would have left a beautiful russian piece of history in original condition, but to each his own. In your case, for sure if you are putting a scope ontop of it, opt for the PU sniper turned down bolt if you can find one. My Russian PU sniper bolt is as smooth as a Krag Jorgensen bolt. Also, if possible to add onto a mosin, a Dragunov SVD flash hider would top it off. Good luck with her, very nice rifles.
