The Trijicon AccuPoint features advanced fiber optics and several intelligent features that make this scope the right choice for all light conditions and even the harshest environments. All models in the AccuPoint Series operate battery free-eliminating the potential for failure during critical moments in the field. They also feature Trijicon's Manual Brightness Adjustment Override, which allows you to control the light output of the fiber-optics during daylight. AccuPoint riflescopes include other advanced elements like multi-layer coated lenses for superior light transmission with no distortion, quick-focus eyepiece, long-eye relief, and precise windage and elevation adjustments. The AccuPoint's rugged construction protects it from the toughest elements. It's crafted from aircraft-quality, hard-anodized aluminum with a tube that's nitrogen-filled to prevent corrosion and eliminate fogging. A solid black-matte finish eliminates glare and light reflection, which could spook game. It's water resistant, so the AccuPoint is able to handle even the most challenging hunting conditions.Ideal for big game hunts or anytime you expect to shoot at shorter distances, the Trijicon AccuPoint with its patented illuminated aiming point will help you get the job done. The scope is illuminated through the use of fiber optics and tritium, providing a vivid aiming point without the need for batteries. Features: Always on, always ready - fiber optics in this riflescope automatically adjust the brightness level and contrast of the illuminated reticle to available light conditions and a tritium phosphor lamp illuminates the reticle in low-light or no-light Aircraft grade aluminum housing - all-weather rugged construction protects against the toughest sporting and outdoor elements Second focal plane reticle - reticle size remains constant as magnification increases, which provides a more exact aiming point at higher magnifications Detection avoidance - the AccuPoint's unique illumination technology provides zero forward emission, so the reticle does not project light through the objective lens Magnification ranges for any application - allows the user to adjust the magnification level to situational needs - like hunting, competitive shooting, recreation and duty applications Outstanding clarity and light transmission - fully multi-coated, broadband, anti-reflective glass provides outstanding target definition in any lighting condition "Both eyes open" design - the illuminated reticles allow you to shoot with "both eyes open" for better target acquisition Easy-to-set adjusters - allows user to easily adjust windage and elevation, choice of capped or exposed adjusters Fiber optics and tritium power and illumination source 10 feet submersion depth
