A variable intensity red reticle is optically superimposed on the green intensified image, providing an extremely visible, high contrast, accurate aiming capability. The Ranger features a unique drop-down eyepiece design that is particularly suited for weapon mounting on the carrying handles such as the M16A2. A separate knob controls reticle brightness. Reticle design can be matched to weapons requirements. Windage and Elevation are controlled by ballistic knobs matched to the objective magnification.
Objective focus is controlled by a focus knob located on the side of the system body.
The objective protective cover includes a built-in training filter that allows use of the system during daylight hours for bore sighting to the weapon. Other custom mounts are available upon request. Ranger is constructed of a high strength composite polymer for ruggedness and lighter weight. The system contains a replaceable, screw-in desiccant indicator and is equipped with a nitrogen purging valve. The Ranger M993 includes 4X objective lens magnification.
