Trijicon AC50010 DI Fiber Optic Set Green - Handgun Replacement

The Trijicon AC50010 is a factory DI Fiber Optic Set designed as a direct replacement for the user-replaceable fiber inserts used in Trijicon DI Night Sights configured for handguns. The pack contains 4 green fiber replacement pieces finished with the same proprietary technique used on the legendary Trijicon ACOG, giving your daytime aiming a bright, consistent, and highly visible green aiming point under ambient light while the tritium lamp and sapphire jewel continue to handle low-light performance.

Each fiber is built from a chemical and heat resistant material, so the inserts hold their brightness and color through the heat of slide cycling, holster wear, and prolonged range sessions. Because the DI Night Sight system is user-replaceable, you can swap in a fresh green fiber in the field without removing the sight from the slide, making this a quick, no-tools fix for a worn, broken, or lost fiber rod.

This interchangeable fiber set is intended for the Trijicon DI Night Sight line on handgun slides. It is the OEM Trijicon replacement part, not a universal aftermarket substitute, and installs in seconds. If your existing DI sights have dimmed, cracked, or lost their daytime fiber, this 4-pack restores the daylight-bright aiming point that made the DI system a favorite of duty and self-defense shooters.
