I'm an iron sights/red dot guy but I am wanting to get into (somewhat) long range target shooting and hunting with my Aero AR-10 in .308 16 inch barrel. I would really appreciate suggestions from the experienced people here. Typical ranges will be 100-500 yards but would like to be able to stretch out to 800 sometimes although this isn't a dealbreaker at all. My priority is durability and ability to hold zero as I can be a bit rough on my rifles. FOV is also important to me because most of my hunting shots would be less than 200 yards. my budget is $1,300. I know I can't get the best for that price but it's what I can afford. My current thoughts are a 4X ACOG, Vortex Razor HD 1-6, Zeiss Conquest V4 3-15, or a Leupold VX-5HD 3-15 but I don't know what I'm doing. Thanks in advance.
