Not sure you should really put a rear sight on this very accurate rifle, but Sako made them to mount on the rear of the receiver. They are available now and then on Gunbroker. Com or Ebay - $100 - $200 At this point I would ask why... on possibly the most accurate 22 centerfire in the world... would you want to use metalic sights?
Considering it's range is aprox 275 yards, why don't you consider putting a 10 -16 power scope on it, and actually benefit from it's potential David Henzler.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
