Well I bought a set of XS Ghost-Ring sights for my 91 quite a while ago and finally got around to installing them. All I can say is I wish I had done it sooner. The sight picture and ability to acquire my target it is much improved over the stock sights. Since I have no intention of mounting a scope on this rifle the XS Ghost-Ring is a great addition. If you've ever considered it you might want to get a set. Money well spent. Now for more range time with the set up.
