The TruGlo TG131XT TFO sight set combines tritium and fiber optic technology to deliver consistent target acquisition in any lighting condition. This dual-illumination system provides the brightness of fiber optics during daylight hours and the reliability of tritium for low-light situations.
What Makes This Different
The TFO (Tritium/Fiber-Optic) design eliminates the need to choose between day and night sight systems. While standard tritium sights can appear dim in bright conditions and fiber optic sights become invisible in darkness, this hybrid system automatically adapts to ambient light levels. The Swiss tritium vials maintain their glow for over 12 years, while the fiber optic elements gather available light for enhanced visibility.Key Features
