Burris combines a 120 Lumen light with a laser aiming device to provide an unbeatable combination of accuracy and quality. Unit has ambidextrous controls and allows use with flashlight only, laser only or flashlight and laser together. Runs on a 3 volt lithium battery (included) for more than an hour of continuous use. Waterproof, fogproof and shockproof. Want to sell due to me wanting a varmit rifle.
