Trijicon Suppressor/Optic Height HD XR Night Sight Set Features The Trijicon Suppressor/Optic Height HD XR Night Sight Set builds on the proven HD Night Sight line engineered for advanced target identification and engagement at increased distances. The self-luminous three-dot configuration pairs a green tritium front sight with a yellow photoluminescent outline against a green tritium rear with a black outline giving the shooter an unmistakable visual reference in both bright and low light. The domed sapphire and tritium front sight is twice as bright as earlier HD designs which speeds up sight acquisition when seconds matter. The suppressor and optic height profile means the set clears a mounted optic or suppressor without requiring a separate set of irons for co-witnessing. The rear sight s angled serrated U notch reduces glare and keeps the shooter s focus locked on the front sight post rather than fighting reflections off the rear blade. A thinner front sight post widens the usable field of view around the front sight letting the shooter track a moving target and spot hits at extended range more easily than a bulkier post allows. Machined from steel and finished in black the frame is built to stand up to duty and competition use over years of service. Designed to fit the Glock 42 43 43X 43X MOS 48 and 48 MOS this set is purpose built for law enforcement and civilian shooters who need a dependable precision upgrade over factory sights.
