The Nightforce scopes in general are great scopes and will do the job. I have been playing with a Nightforce 2.5-10x32mm in my hands but have not used it yet. I really like the 0-stop feature on them, the glass is outstanding, the construction is very robust, and they look great. We have sold a few to our customer and they all really like them.
As for the reticle you can get a few choice. I only recommend two of them, the MIL-DOT and the NPR2 (MOA based). Iím a big fan of MIL on MIL and what I mean by that is I like a MIL Elevation and Wind turret with a MIL reticle.
I have a Sako that I would like a to put one on but it has a good scope on it already.
Here one I mounted to an AR10:
