The Meprolight ML63144 Fiber-Tritium Bullseye is a compact, low-profile optical pistol sight designed for CZ Model 75 and 85 dovetails. It produces an illuminated dot and circle aiming point using a fiber-optic element paired with premium-grade tritium, providing visibility across a wide range of lighting conditions without batteries. The sight is intended to replace the front sight on compatible pistols and to fit most existing holsters. Note: the product literature explicitly states it is not for the SP-01 model.
