Looking for some insight on which tactical scope to purchase for my next Tactical Rifle purchase. Whether a Nightforce NXS 5.5-22x50 illuminated or the Leupold MK4 6.5-20x50 LR/T M1 illuminated. I just want to hear some real world reviews; durabaility, ruggedness, reticle quality, things of that nature. Any help would be appreciated, thank you in advance.
