I have NF nsx 5.5-22x56 with high speed turrets and zero stop. It was purchased from a buddy of mine about one year ago and for some reason when he bore sighted his rifle he reset the zero stop. Needless to say he unscrewed the allen head screws all the way out along with the clutch. The scope will need to be sent back to NF to be setup again. Original box, papers, etc... etc. included. Its mounted on a set of Aadland triple lug rings which ill also included for a additional $100. EVERYTHING is brand new. Please TEXT me with any questions and for pictures 704 791 7138.
