The Viridian REACTOR R5-R Gen 2 red laser sighting system offers cutting-edge performance in a sleek, easy-to-install package. Designed to blend seamlessly onto the trigger guard, it maintains an invisible profile for a smooth and efficient draw. Utilizing a 635-650nm laser wavelength, Viridian's red lasers deliver the brightest, sharpest red-dot available for superior accuracy. Featuring two modes of operation constant and strobe this laser offers up to 12 hr of battery life for extended reliability. The Gen 2 models include a custom-fit, ambidextrous inside-the-waistband (IWB) holster equipped with Viridian's INSTANT-ON activation. This advanced feature ensures the tactical light is immediately activated when you draw your firearm no buttons, no squeezing, just a reliable, immediate response every time you need it.
