When it comes to tritium gun sights, aluminum sleeves and painted-on white rings are the conventional choice. Night Vision breaks the mold literally. Our patented injection-molded sleeve design not only securely holds our tritium vials in place but also creates a brighter and more durable ring that we refer to as The Perfect Dot. This innovative design ensures maximum visibility, allowing for quick and precise target acquisition both day and night. With Night Vision, you can count on superior performance and reliability in any lighting condition.
