Just dont buy the cheap ~$60 Bushnell ones. I started with a cheap AIM 4x 40mm scope, then saw the Bushnell rimfire on sale for cheap cheap (like $37 I think I paid) and liked the idea of a variable power for the range and the 32mm objective seemed like it would be a good size for a grouse gun. I dont know what it is, but my groups were better with the 4x AIM scope than this one.
At this point, I think Im going to put the bushnell that came on my Savage Axis onto it. Its a 3-9x40, a bit bigger than I would probably like but its a step up in quality from the crappy bushnell rimfire scope.
