Trijicon Glock Suppressor/Optic Height HD XR Features The Trijicon Suppressor/Optic Height HD XR front sight uses a domed sapphire lens over its tritium lamp to produce a sight picture that is twice as bright as the standard HD night sight helping the shooter pick up the front sight faster in a dynamic engagement. A thinner front sight post opens up the shooter s field of view making it easier to track a moving target and confirm hits at extended distances. The green tritium front lamp carries a bold orange photoluminescent outline that charges under ambient light and glows for faster acquisition even before the tritium takes over in full darkness. Both law enforcement and competitive shooters benefit from this extended target identification at range that the HD XR line was designed to deliver. The rear sight is an angled serrated U notch design with a black outline around its own green tritium lamp cutting glare off the rear sight blade so the eye naturally settles on the brighter front sight. This set is built to suppressor and optic height specifications giving proper co-witness clearance on a Glock MOS slide running a mounted red dot or a suppressor. Steel construction on both the front and rear sight bodies stands up to the recoil and holster wear that duty and competition use demand. Local and federal law enforcement along with pistol shooters who need a more precise sight picture in any light can count on the Trijicon Suppressor/Optic Height HD XR Night Sight Set.
