The Meprolight FT Bullseye Rear Sight (brand part number 631053108) is an extremely small, low-profile optical pistol sight built on an optical illumination patent, giving shooters a reflex-sight-style aim point in the form of an illuminated dot inside a Bullseye circle. The fiber-optic and tritium combination works in all lighting conditions with no batteries needed: fiber optic gathers light for bright, daytime shooting, while premium-grade tritium delivers instant illumination at night or in low light. Installation is simple on an existing pistol dovetail, and because the FT Bullseye eliminates the need for a separate front sight, it fits most existing holsters without modification. This version is built specifically for Glock MOS standard-size models.
