When it comes to tritium gun sights, aluminum sleeves and painted-on white rings are the norm. Night Fision breaks the mold, literally. Their patented, injection molded sleeve design not only holds their tritium vials securely in place, it creates a brighter and more durable ring, they call The Perfect Dot, that provides maximum visibility both day and night.
