I am pretty sure I could mount my old Weaver scope from the 50's and kill moose all day long here in Alaska. The glass on my Nightforce 3-10x42 SHV is clear to me and it moves where it is supposed to when I need to adjust the point of impact. But, I don't think the glass is optically any better then the glass I had in a Leupold VX5 2.5-10x42. But, the adjustments were not as reliable as the Nightforce.

I have never owned a Top Tier scope and if I had that kind of money for optics it would be used to up grade my binoculars, which are a pair of 10x40 Zeiss Classics I have used for many years.
