Mine with Ghost Rings Sights, Needed some adjustment to suit my eye... Mostly in the windage adjustment. To me I dont see the Ghost rings to be that accurate, that you can adjust out a couple of inches here and there. Also doesn't it depend on the ammunition you are going to use weather or not they would correspond with the ballistics of the ammunition?
My advice is to load up your favorite ammo, start out at a shorter range and adjust from there. I never have expected much from the "factory" having my sights adjusted for me in the past with any gun, nor will I ever. YMMV
