- CNC-machined steel construction
- No batteries required
- Snag-resistant design
- Glows in the dark
TFO gun sights from TRUGLO are the most revolutionary innovation since TRUGLO introduced fiber optics. TFO refers to the patented combination of Tritium and Fiber Optic technologies. The Tritium maintains the brightness level of the sight in low-light (or NO light) conditions. That means you can see your sight even in complete darkness with perfect transition through all lighting conditions. Tritium does no need batteries and does not need to be charged with light- it simply glows.
