Mine was pretty rough when I picked it up in an auction for $110, with the rear sight. Don't hate the player, hate the game. I cleaned the stock with Murphy's Oil Soap and applied multiple coats of tung oil. I took the action components and the bolt from a 1983 vintage model 60 and put them in the 99M1 side plates. Shoots great.
If I didn't have the rear sight, I would remove the front sight and pay my local gunsmith to drill and tap a hole and install tech sights.
