Welcome to the 21st century.
Companies have no sense of tradition, no sense of honor, no pride.
Since they say it can't be fixed, I would trade it off, buy something else, and spend a little spare time lighting them up good and proper on every shooting website I could find.
If you can't bring yourself to letting the rifle go, I would consider trying to contact Sako directly. It's possible that they may still give a rat's ass about their reputation.
