Trijicon DI Night Sights Fiber Optic Replacement Pack - Green

The Trijicon DI Night Sights Fiber Optic Replacement Pack in green gives you a way to refresh or customize your DI sight setup without buying a whole new sight set. If you're running Trijicon DI night sights on a duty gun, range gun, or defensive carry pistol, these replacement fibers let you keep your sights performing at their best. This pack includes four green fiber replacements, so you've got spares for the range or field use.

What sets the DI system apart is the interchangeable fiber design—something Trijicon patented to solve a real problem. Rather than being stuck with whatever came on your sight, you can swap fibers in the field and choose from different colors to dial in exactly the sight picture that works for you. The fiber itself is built tough: it's heat and chemical resistant, finished with the same proprietary process Trijicon uses on their ACOGs, and paired with a tritium lamp capped by a sapphire jewel. That dual-illumination approach means your aiming point stays bright from bright daylight through low light and total darkness.

These are purpose-built for shooters who don't want to compromise on any-light capability. Whether you're training hard, competing, or carrying for defense, the DI system delivers the brightness of fiber optics with the always-on reliability of tritium. The green fiber option gives you a crisp, visible aiming point that many shooters prefer for daytime and intermediate light conditions.

Frequently Asked Questions

What pistols are Trijicon DI Night Sights compatible with?

The facts provided don't specify which pistol models these sights fit. Check your current DI sight installation or contact us to confirm compatibility with your firearm.

Can I swap fiber colors in the field with this design?

Yes. The DI system's interchangeable fiber design lets you change fibers in the field, so you can customize your sight picture or swap in a fresh fiber if needed. This pack gives you four green fibers to work with.

Do these fibers work in low light and darkness?

The green fibers collect and amplify light for daytime brightness, but the sights also feature a tritium lamp underneath. That tritium provides a constant aiming point in low light and complete darkness, so you get reliable illumination across any lighting condition.

What makes the DI fiber durable?

The fiber is heat and chemical resistant and finished with the same proprietary technique Trijicon uses on their ACOG optics, so it's built to handle hard use and environmental exposure.
