The Night Fision GLK004013WGZ suppressor height sights for Glock deliver a brighter, more durable aiming solution with their patented Perfect Dot injection molded sleeve that houses Swiss tritium vials and creates a clearly defined daytime ring for fast target acquisition. Built to endure, these CNC machined steel sights feature a black nitride coating for enhanced wear and corrosion resistance, ensuring dependable performance in harsh conditions. The Green Tritium with a White Outline Front sight combination provides maximum visibility day or night, making them an ideal upgrade for Glock 17, 17L, and 19 platforms with suppressor height sights. Installation is recommended by gunsmiths, reflecting the precision engineering behind this Night Fision design, which is proudly built in the USA. The innovative sleeve design not only secures the tritium but also elevates the overall brightness of the ring, giving shooters a reliable aiming reference that remains consistent across lighting changes. Whether on duty, at the range, or in rugged outdoor environments, these Night Fision sights offer rapid sight picture and improved contrast for quick, accurate shots.
