For added discretion in professional units, having an IR laser is the perfect addition for nighttime use, and the Holosun LS221 Visible and IR Laser Sight provides the versatility needed for mission-oriented units to get the job done with night-vision equipment. Built as a coaxial unit, each laser is adjusted with the same elevation and windage adjustments. The lasers are protected inside of a machined aluminum housing and are operated through a cable switch included with the product. Each laser is built with a CR123 battery. Mfg: Holosun
