I have an AR with 16 inch stainless barrel that currently has a 3-9x40 VXR patrol on it. I'd like to upgrade the scope to something this is a bit more versitle. I'd like to have a bit more field of view on lowest power and some more magnification on the high end so I can dabble in some long range shooting. I'd like the scope to have an illuminated reticle and an elevation turret with a zero stop. On paper the Nightforce nx8 2.5 - 20 looks perfect except for the weight. I'd like to stay a bit lower on weight then 28 Oz. Is there any other options I should look at?
