DESC: The Mars6x-4 night vision riflescope was inspired by ATN's quest for technical perfection. Scientifically advanced materials and components were assembled into this battle-ready sighting system that is well suited for tactical and sporting maneuvers. This Mars scope features a 6x magnification for precise long range shooting as well as a reasonably wide field of view for quick target acquisition at close range. The mechanics of this optical sight are well thought out and built to exacting tolerances; focusing the scope is facilitated by turning the top mounted knob, and comfortable target turrets engage precise 1/4 MOA windage & elevation correction.
