Costa Ludus sights boast a distinctive sight picture, featuring a proprietary Night Fision perfect Dot in the front sight and a horizontal tritium bar in the rear sight. Serrated to reduce glare, their shorter height ensures minimal interference with your dot for a streamlined co-witness. Using our patented injection molded sleeve design with ballistic materials, our tritium vials are securely held in place. Night Fision night sights exceed the tritium content of typical market options, coupled with a domed lens for a sharp and well-defined glow.
