Darn for that kind of money, you could probably sell your current gun, get SA's Range Officer, and still be ahead. The RO's fit is to the standard of their TRP and Trophy Match. It has nice adjustable sights as well
Here's mine:
Otherwise, I believe that LPA makes an adjustable sight that fits the "GI" dovetail. That your front dovetail does not appear to be a Springfield cut is probably a good thing as their dovetail is a unique size.
