US Optics and Night force seem to be the de facto standard. I use a night force as it's the most scope I can afford. I like the EREK knobs and 58 mm Objective of the US Optics just cant afford it. Recently a company called IOR has gotten my attention. Wish I knew someone who had one supposedly Schmidt and Bender Glass quality with Nightforce toughness for less that 1700 bucks. If That is true I know what my next scope will be.
Also the SWFA SS HD line is supposed to be outstanding glass it's at the 1k-1.4k Price point, along with the MK4's Weaver Tactical etc.
If you got the cash a S$B would serve very well.
It all comes down to what you’ve got to spend.
