The Trijicon HD XR Suppressor/Optic Height Night Sight Set delivers professional-grade mechanical precision and rapid target acquisition to the Springfield Armory Echelon platform. This specialized sight set utilizes an ultra-thin 0.122-inch front sight blade that significantly expands your downrange field of view, making it much easier to identify targets and track hits at extended distances. The front sight houses a bright green tritium lamp encircled by a high-visibility, photoluminescent yellow outline that aggressively draws the eye during high-stress daylight scenarios. Purpose-built with an elevated profile, these sights seamlessly clear attached suppressors and provide a perfect co-witness backup layout when running slide-mounted reflex optics like the Trijicon RMR. Precision-machined from heavy-duty steel and cushioned with silicone rubber to survive harsh cleaning solvents and intense slide vibrations, the rear sight is capped with an angled, serrated U-notch profile to minimize glare and facilitate emergency one-handed slide manipulations.
