Trijicon DI Night Sight Set

The Trijicon DI Night Sight Set is the first of the industry to feature Tritium and Fiber Illumination for any light aiming. It was built on Trijicon’s proven engineering and manufacturing excellence in tritium and fiber optic aiming solutions. It is designed for users who want daylight brightness and a constant aiming point. The patent pending design not only allows the users the ability to replace the fiber in the field, it allows the user to choose among several fiber and ring retainer colors to configure a personalized aiming solution.

The night sight features a chemical and heat resistant fiber, finished with the same proprietary technique as the Trijicon ACOG, coupled with a tritium lamp capped with a sapphire jewel. This dual illumination technology amplifies collected light, ensuring an ultra bright aiming point in any light from daylight bright to low light to complete darkness. Trijicon DI Night Sights offer users the unique features needed for an any light pistol aiming solution, with the durability and reliability Trijicon is known for. It is available for Glock, Smith & Wesson, Sig Sauer and Springfield.
