This kit provides quick and accurate target acquisition in low light for your medium and close range shooting needs. Use the flashlight to find your target, then use the laser to lock on. The laser is rated at 100 yards of visibility at night and 25 yards in daylight and is adjustable for windage and elevation. The flashlight illuminates targets from 30 yards. Both the laser and flashlight are equipped with tactical on/off pressure switches and the whole kit easily mounts to 20mm picatinny rails. The kit also comes with a red filter and lens cap for the flashlight and batteries!
