At that range I would just go with an RDS aimpoint, trijicon or eotech maybe add a 3x magnifier. There is no need to dial, if you want magnification consider a 1-4. 1-6,1-8,1-10 from Horus vision, Bushnell, Trijicon, Vortex, US optics, Nightforce, Premier Recticles, Kales, Meopia there are more of course. Here are some examples. I am waiting on new US optics 1-10.Hi I'm new to AR's and need a scope that is good for making accurate shots out to 200 yards but I also don't want it to be too big because I want to keep the tactical look. Any suggestions?
