Very good quality built to last. Ambidextros on off switch make it easier for anyone. The 3 position toggle switch to go between sight, flashlight or both. The fllashlight has strobe mode which can be used for signaling or to disorient the objective. A great price for a good sight. The high intensity green lazer projects a distance greater than 300 meters. A nice addition to your firearm. Comes with battery and protective carrying case.
