TFO gun sights are the most revolutionary innovation since TRUGLO, Inc. introduced fiber optics. TFO refers to our 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.

TRUGLO is committed to providing our customers with innovative products containing quality and value added features for Archery, Crossbow, Optics and Firearms. TRUGLO…When Brightness Counts!

Note: NDZ always recommends any part be installed by a qualified and trained gunsmith. NDZ promotes the use of safety practices and gear when working on any firearm.
