Nightforce scopes are made here in Orofino Idaho but they do not make there own glass they purchase it from the same company that Bushnell does for the Elite 4200, 6500, and the Elite HDMR. I personally own 2 4200's, a 6500, and a Nightforce, opticaly there is no difference, dont beleive me go to a store that carries both and look at it for yourself.
