Trijicon's AccuPoint riflescopes are based on Trijicon's battery-free, dual illumination technology. The precise, triangle-shaped, tritium-illuminated reticle helps ensure optimum brightness in low light, and a fiber optic collector automatically adjusts the brightness of the aiming point to existing light conditions. The BIndon Aiming Concept allows a marksman to lock onto a moving target more easily and more quickly that with a traditiional riflescope.
