Now up for auction: a U.S. Military “ART-II” Sniper Scope with mount for the M21 (M14) Sniper Rifle. NOTE: Auction ends May 8, 2011. It is a heavy duty 3x-9x variable power scope built by Leatherwood. This scope is in good condition with external wear and part of the serial number tag is missing (see pictures). The optics are generally good but there is some internal spotting on the lenses which leaves a slight dark “ghost” in the sight picture (most at about 10-o’clock). Crosshairs are in good condition and the lenses do not have any external chips or scratches. The zoom ring turns smoothly and appears to operate properly. Comes in the military case complete with latches and gasket (there is a different scope/rifle# written on case). Also included are a photocopy of the operator’s manual as well as the 1999 dated CMP purchase document.
