It will say what all they did on that blue sheet they send back with the scope.
I should add that for me they have changed parts, lenses, and updated scopes when they had them for leaks or repairs, but they've never charged me for anything except what I originally sent it in for.
On one, they apologized that they didn't make parts for one that old anymore, but they were able to fix some internal problem they had found upon inspection, by putting all new guts in it. They basically upgraded the scope to a newer model, but it still had the original model number engraved on the bell.
