The Trijicon HD XR Night Sights are specifically engineered to meet the evolving demands of law enforcement agencies, offering advanced target identification and engagement capabilities at greater distances. Building on the success of the original HD Night Sights, the HD XR features a thinner front sight post, providing shooters with a wider field of view. This enhancement allows for quicker target identification, faster engagements and better visibility of hit locations at longer ranges. Perfect for pistol shooters who require precision in any lighting condition, the Trijicon HD XR Night Sights deliver reliable performance in low-light and no-light environments. The green tritium lamps are backed by a 12-year warranty from the date of manufacture, ensuring long-lasting illumination.
