PRECISE POINT OF AIM Highly accurate, Liberator maintains its precision zero over time. CRISP ILLUMINATION The 3 MOA red dot is large enough to grab the eye quickly, yet small enough to take precision shots to 200 yards. Ten brightness settings keep you prepared for any lighting environment. FAST TARGET ACQUISITION True 1 x allows for a lightning quick sight picture. Strike faster! The included CR2032 battery can last for 3,000 hours on a medium setting. After 4 hours without movement, Liberator's Auto-Off feature shuts down the red dot to further save battery life. Pressing the brightness increase button will awaken the Liberator, instantly returning to the previously set brightness level.
