I mounted a Sightron I 3-4x40 on my Knight Wolverine LK-II and it has outstanding clarity and focus. I really like this scope. No matter what you sight on at what distance, there seems to be no re-focus necessary and the light gathering ability of this scope is just plain impressive. I got the scope for $129.00 and it is as nice as many of the more expensive scopes I have on some of my center fire rifles...
