I am in need of some help deciding on an optic. The rifle is a r700 sps tac in .223 and will primarily be shot at 100 yards and once in a while out to 3-400 yards. After looking through some scopes at a store I really liked the way the trijicon accupower glass looked, however, there are very few to no reviews online regarding the 4-16x50 model. I have found it online for $700-$800 and I am also considering buying a used leupold Mark 4 4.5-14 with m1 sfp for around the same price. I have not looked through a Mark 4 before, but the glass on the leupold vx3 I looked through at the store seemed pretty good as well. I was looking at the vortex offerings around this price range, however, to my eye the glass was not as good and for what I will be doing I don't really think I need a ffp or zero stop. The exposed vs capped turrets I can take or leave. If there are any other recommendations I should be considering please let me know. Thank you for the help.
