For me, I wouldn't go with a fine crosshair reticle since I am not a bench rest shooter. I don't like 1" tubes and that is what is on the Nikon Monarch that and the 30mm tubes just perform better under adverse conditions. I like the Mil systems. I have had Nikon Monarch in the past and the ones that I used had problems with longer ranges past 500 yards. The Nikon also did not do very well in heat when I was more likely to encounter mirage. If it were my gun, Nikon Monarch wouldn't even be in the running for consideration.
Depending on your shooting style, I would look at a different scope. If you are set on Nikon, I would look at their tactical models like the Monarch X. Invest in a good set of rings and base for your optics. As for the gun, thumbs up on that one.
