Considering options for what to do to upgrade my Axis 2 Precision.

What are some good options to improve the bolt? Mine is very rough. Wouldn't mind a better handle.
I've seen a bit on the extractor, but not that concerned with that.

Primarily looking for something to improve how smooth it opens and closes as well as how it extracts from the chamber, since it basically doesn't now.
Not sure I can really fix the extraction issue unless it somehow isn't clearing the lugs for some reason. But that's another question.
