I see quite a few 77 RSI with the rear sight removed to accommodate a scope but I've never seen a rear sight for sale. Where did they go? Have I just missed all the listings? What is a fair price for one?

I paid $60 awhile back, but it was perfect and as-new. I expect well under a benji today but I remember passing on an abused one - back when one could find such things at gun shows.
