Glowing bright both day and night, TFX sights are always ready. TFX takes TruGlo's award-winning Tritium + Fiber-Optic technology even further with all the features customers requested: compact snag-free design, longer sight radius, and amazingly durable construction built to handle just about anything. Illuminating elements are encased inside a virtually indestructible chemical and shock-resistant capsule and the CNC-machined steel is protected with a rust-proof FORTRESS FINISH. There is even a highly visible white ring surrounding the front fiber to make it even more visible, encouraging the eye to rapidly focus on the front sight for a fast and accurate sight picture. TFX sights will amaze even the most discriminant shooters.
