I just traded a Swift 4X12 for a Nikon Prostaff 2x7 on my .17HMR and could not be happier. That little sucker is so sharp and clear, I can see those little holes in a target at 100 yds on 7 power. I feel Nikon is really building some nice optics for the money. I say this because I was seriously considering a Burris compact for this gun until I compared them side by side, set at the same power. 1/2 the price for a brighter clearer sight picture, pretty easy decision.
