Night Fision Orange Front U Notch Rear Night Sight Set for Fn 509

The Night Fision Night Sight Set Orange Front U Notch Rear for FN 509 delivers a high-visibility, precision sighting system built around Night Fision's patented injection molded sleeve design that securely holds their tritium vials in place with ballistic materials, ensuring durable performance under demanding field and range conditions.

The installation is recommended to be performed by a gunsmith, aligning with the precision required for reliable zero and consistent sight picture. Built in the USA with Swiss tritium, this orange front and U-notch rear configuration is designed to enhance fast, accurate aiming across a wide range of lighting conditions, making it an excellent choice for duty, competition, or personal defense scenarios where quick target focus and reliable illumination matter most.
