The Ed Brown HD XR front night sight is engineered to meet the demands of tactical shooters requiring a precise sight picture with enhanced visibility under all lighting conditions. The sight features a green tritium night element encircled by bright photo-luminescent paint, providing optimal visibility both day and night. It is designed to seamlessly retrofit any Ed Brown 1911 currently in service. When paired with any style of plain black rear sight, this configuration significantly enhances visibility and accelerates front sight acquisition, even in transitional lighting environments. The green tritium lamps are covered by a 12 years warranty from the date of manufacture, as provided by Trijicon.
