For 3-18x that I am assuming you plan to use at longer ranges out west where wind, elevation, and angles will matter, I would want a first focal plane scope with mil (or moa if you prefer) turrets/reticle and not a ballistic elevation turret with a duplex.
For similar money you could get a Nightforce SHV, Maven RS 1.2, Trijicon tenmile, etc.
