The Night Fision Tritium Front Sight (brand part number GLK-000-001-OGXX) is a green-tritium, orange-outline front sight built for the Glock 17, 17L, 19, and 22. Night Fision packs more tritium into the vial than most night sights on the market and caps it with a domed lens that collimates the tritium rays into a crisp, defined glow instead of a diffuse blur. The company’s patented injection-molded sleeve, which it calls the Perfect Dot, holds the tritium vial securely while forming a brighter, more durable ring around it for maximum visibility day or night. The sight body is CNC-machined from high-quality steel and finished in a Black Nitride coating for wear and corrosion resistance, then built in the USA with Swiss-sourced tritium.
