The Pistol/Rifle Laser Sight mounts to any standard rail with its integrated mount, and gives you a red sighting laser with up to 500 meters of distance. The Pistol / Rifle Red Laser Sight is a rugged device with a body made of aircraft grade aluminum, and at a mere 2 ounces of weight, it won't throw off your weapon's balance. Use the end cap switch for continuous on, or the pressure switch for momentary-on. The Pistol / Rifle Laser Sight features a Weaver-style mount and allows for elevation and windage adjustment.
