The scope of the future. If you are shooting from moderate to close range, it is unbeatable. Ypu can even shoot "from-the-hip" accurately. It projects a laser beam that looks like a small red dot onto your target. The sight can be adjusted for windage and elevation. It comes with two sets of mounting rails: one for .22/Air Rifle and two "Weaver style" bases. It has two different switches, one on top of the body and the other is a momentary pressure sensitive switch and wire that can be mounted on the gun where ever you would like to put it.
