Depends entirely on the use you intend to put the rifle to.

Hunting, extreme long range, silhouette, a compromise of all or the above? And where are you hunting? Woods, fields, plains. How many seconds do you typically get between spotting game and needing to take the shot.

For hunting I like the Nikon Prostaff and Monarch scopes. Good glass at a reasonable price for the "sight-it in and don't futz with the turrets thereafter" hunter.

If you want a mil-dot or MRAD that you chase the turrets up and down each shot you'll need the input of others.
