when I worked at Cabela's it was said that the same people that made the Cabela's Alaskan guide scopes also made the Sightron scope. for the money the Alaskan guide scopes were pretty good. I had a 4.5 to 14 x 44 mm scope on my Ruger # 1B in 22-250. my only complaint was they were a little on the big side. it would have been just as good if it was a 40 mm. no trouble at all seeing 22 caliber holes at 100 yards
