The TruGlo TG131GT1 TFO sight set combines tritium and fiber optic technology to deliver consistent target acquisition in any lighting condition. This dual-illumination system automatically transitions from bright fiber optic visibility in daylight to reliable tritium glow in darkness.
What Makes This Different
Unlike single-source illumination sights, the TFO system features both tritium capsules and fiber optic rods in the same housing. The fiber optic elements gather ambient light during the day for maximum brightness, while Swiss tritium provides a 12-year guaranteed glow for low-light situations. This eliminates the need to choose between daylight visibility and night performance.Key Features
