I'm moving my 2.5-10x32 NXS to one of my 16" AR's. If you were buying an optic to get as much range and accuracy from a 5.56 AR as possible, which would you chose? Im looking at the 4-16x42 f1 ATACR and 3-18 Razor. Should I be looking for higher magnification or is 16x enough? I'm sold on the tracking and ruggedness of the Nightforce. I've looked through both and they seem equal optically. I read that the Razors are a favorite with the prs crowd but is it as tough as the NF? Anybody have both? Anything better in the $2-2.5k range? Tracking and toughness are my main priorities. Possibility of a MWS later this year so I guess I need to consider max range for 308.
