The TruGlo TG13WA4A Brite-Site TFX sights combine tritium and fiber-optic illumination to deliver a visible sight picture in both daylight and low-light conditions. The design encloses illuminating elements in a shock- and chemical-resistant capsule and uses CNC-machined steel components finished with a rust-resistant Fortress finish. A high-visibility white ring surrounds the front fiber to encourage rapid focus on the front sight for quicker, repeatable alignment.
