When it comes to tritium gun sights, aluminum sleeves and painted-on white rings are the conventional choices. Night Fision 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 call The Perfect Dot. This innovative design ensures maximum visibility, allowing for quick and accurate target acquisition both day and night. With Night Vision, you can rely on exceptional performance and clarity in any lighting condition.
