If money was no object, what is the best scope you can buy?
If cost equates to value... then the Carl Zeiss Optronics Hensoldt ZF 6-24x72 SAM, at a bit under $12,000 would be the "best".
Best is a relative term... best for what?
I tend to go with what I know. Leupold, March, IOR Valdada and US Optics.
