Trijicon HD XR Tritium Night Sight Set Features The Trijicon HD XR Tritium Night Sight Set builds on the proven HD Night Sight platform with a self-luminous three-dot design engineered for the next level of advanced target identification and engagement at extended distances. The domed sapphire and tritium front sight is 2X brighter than earlier HD designs helping shooters acquire the sight picture more quickly under stress or in low light. A highly visible photoluminescent paint outline surrounds both the front and rear sight elements soaking up ambient light to stay bright even without direct illumination. This combination of tritium glow and photoluminescent paint gives law enforcement and competitive shooters a dependable aiming reference in any lighting condition. The rear sight uses a U-notch design that is angled and serrated to reduce glare and help the shooter s eye stay focused on the front sight rather than getting distracted by reflections off the rear. A thinner front sight post opens up the shooter s field of view which further improves the ability to identify targets and confirm hits at longer distances. Built at suppressor and optic height the HD XR set is designed specifically for the Smith and Wesson M&P C.O.R.E. and M2.0 Optics Ready pistols running a mounted optic or suppressor. Finished with a steel frame in Black this Trijicon HD XR set gives duty and competitive shooters a precise dependable sighting system for fast accurate engagement.
