Three choices of reticle colors (red, green and blue) make it easy to line up the 5 MOA dot on a sneaking tom against any background. A remote pressure switch and extended cord make it quick and simple to turn on and off with almost no extra motion. The 30mm objective lens gathers extra light for better visibility at dawn and dusk. An adjustable rheostat lets you set the brightness of the reticle to match the conditions. Click windage and elevation adjustments make it easy to perfectly pattern or sight in your gun. Includes optical-quality, see-through, flip-up lens caps and a 3V-CR2032 battery. Limited lifetime warranty.
