I'm looking to buy a scope and I'm torn between 4 different scopes. From what I have heard so far the Weaver is just as good as the Burris Signature and Nikon Monarch, both $150 more. The Bushnell 4200 is around the same price as the Weaver. How do these two cheaper scopes compare to the two more expensive scopes? Any feedback espicially on the Weaver would be greatly helpful.
