Where can you buy a rear sight for a sako vixen rifle?

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
