Any thoughts about the ruggedness of a Nightforce versus a Kahles? I'm considering the ATACR 5-25x56 F1 and the K525i both with the Tremor3 reticle. I know that the military uses Nightforce, but can a Kahles get banged around and still hold up? Any particular likes or dislikes about either? I noticed that the windage is capped on the ATACR.
