I have been staring through lenses most of the time, most of my life. Once you get above a certain quality level, most human beings can't tell much difference.....at least I can't. Computer designed and ground lenses in top quality scopes like Nikon, Leupold, Swarofski, Sightron, Night Force, etc. are all far superior to what was available just a few years ago.

My question is about the mechanical aspects of the scopes. Who makes the most durable, dependable, and repeatable turret adjustments?

Has anyone ever done any comparison tests?
