This tactical light/laser has four lighting modes: light, laser, light & laser and light in strobe mode. The water-resistant body is constructed from aircraft-grade anodized aluminum. Its pressure switch attachment allows you to activate the light with total control, while using the side switch to change light modes. Also included is a fixed-tail cap that lets the light be used without the pressure switch attachment as a normal flashlight. You also get a self-locking and adjusting mount that fits both a vent rib or plain barrel, with no tools needed.
