I,ve owned Leupold, Swarovski, Zeiss, and Nightforce. Each scope has its upside and down side when compared to the others. Leupold is a good scope w/ a side parallax adjustment which I prefer because it requires less observeable movement to make your adjustments .It has good optics ,but not great. I have had problems w/ the parallax knobs coming loose when used on larger calibers. Swarovski makes great glass but I dont care for the front parallax adjustment and they tend to get grit in the parallax adjustment causing the function to become unsmooth which is annoying to say the least. Nightforce are built like a tank. They will last a long time but the optics are not what you find on Swarovski or Zeiss. If money is not an issue and I,m assuming its not since your looking at Swarovski and Nightforce, you may want to consider a Zeiss Diavari. They have excellent optics, and side parallax adjustment. On the down side each click is 1/6th M.O.A. rather than the 1/4 click we are all use to.I currently own three Zeiss scopes . Two are Zeiss Conquest's which you might also consider. The Conquest has the same basic features as the Diavari except the Conquest has 1/4 M.O.A. adjustment. Also great optics, and less in price than the Diavari. Do your homework, and finding what works best for your application shouldn't be to difficult. Especially with all the input from our fellow LRH members. Hope this helps some. May your aim be true and your bullets fly straight.
