Looking for an AR light? How about Green Laser Sights that can universally fit an AR, pistol, or shotgun? Crimson Trace brings the CMR-207 Rail Master Pro Laser Sight and Tactical Light System, fitting any of those if they're outfitted with M1913 Picatinny or similar accessory rails measuring at least 2-3/4 inches. The Crimson Trace Rail Master combines a powerful laser with a 400 lumen LED white light that can be used individually or together. This Crimson Trace laser light combo gives the best of both worlds in one compact, lightweight aluminum-bodied, easy-to-use accessory. There are ambidextrous activation points, not only for great ambidextrous pistol use but also as a shotgun or AR laser sight. A Crimson Trace Rail Master Pro is also programmable for either of 3 modes: laser, light, or laser + light simultaneously. The smart electronics automatically power down the unit after 5 minutes to save battery life but can be instantly switched back on with a tap of the button. The CR123 lithium battery is rechargeable with the included USB cord. The laser component is fully adjustable for windage and elevation, allowing you to get it as close to zero as possible. The Railmaster Pro is available with either a red CMR-207 or green CMR-207G 5mW, 532 NM, Class 3R laser. If you're looking for a rail laser or light, why not get both?
