Redfield 3-9x Widefield rifle scope. This scope has the AccuTrac reticle, an optic model designed for M40 USMC/ARMY snipers. The model was sold to civilians in the mid 70's - to mid 80's before Redfield was bought out by Leupold.
Overall, this scope is in excellent condition. There is some very minor wear from a previous set of scope rings, but no other significant marks of metal damage.
The glass in this scope is bright and crystal clear without any optical issues.
