Trijicon
The Trijicon AC50011 DI Night Sight replacement kit brings field-replaceable fiber optic upgrades to your pistol's iron sights. If you're running Trijicon DI Night Sights and want to swap fiber colors, refresh worn components, or experiment with different sight configurations without buying entirely new sights, this kit gives you the flexibility to do it. The dual-illumination design—combining tritium with bright fiber optics—delivers a sight picture that stays visible from full daylight through complete darkness, and the ability to change fibers in the field means you're not stuck with one look or performance profile.
What makes these replacement fibers stand out is the engineering behind them. Trijicon treats the fiber with the same proprietary process used in their ACOG optics, creating a finish that resists heat and chemical damage while maintaining that daylight-bright glow. The tritium lamp sits under a sapphire jewel, protecting it while letting light through consistently. This is the kind of durability you expect from Trijicon—not flashy marketing, just proven reliability under hard use.
This particular kit includes four green fiber replacements and two black retainers, so you have spares on hand and the option to experiment with retainer color if your sights support it. The included T10 torque L-key ensures you're installing components with the right force—over-tightening or under-tightening fiber optics is a common mistake. Whether you're refreshing sights after years of use, need a backup set of fibers, or want to try a different color configuration, this replacement kit keeps your DI sights running at peak performance.
| Brand | Trijicon |
| Model | AC50011 |
| Type | DI Night Sight Replacement Kit |
| Fiber Color | Green |
| Retainer Color | Black |
| Illumination Technology | Dual (Tritium + Fiber Optic) |
This is a replacement kit designed for pistols equipped with Trijicon DI Night Sights. Confirm your sights are the DI model before ordering, as compatibility is specific to that system.
If a fiber gets damaged or you want to try a different color, you can swap it in the field without removing or replacing the entire sight. You're not locked into one configuration for the life of the sights.
The kit includes a T10 torque L-key, which is the tool needed for proper installation. Using the correct torque ensures fibers are secured without damage.
The fibers are treated with the same proprietary finish Trijicon uses on their ACOG optics and are designed to resist heat and chemical damage. They're built for the same reliability you'd expect from Trijicon sights.
