Used Nightforce ATACR 4-16 x 42 Mil-XT (C615). I bought this brand new last year, and it has light handling and ring marks as seen in pics. Glass is like new and caps were always kept on. Only reason I'm selling is I just bumped up to an ATACR 5-25 as vision is getting worse. $2,000 shipped with original box. Email direct to [email protected].
