Meprolight USA FT Bullseye Rear Sight - Black | Green Tritium/Fiber Optic (631163108)

The Meprolight USA FT Bullseye rear sight brings fast, reliable target acquisition to your pistol without batteries, switches, or electronics. Built on a patented optical illumination design, this compact rear sight combines fiber optic and tritium technology to keep you on target in any lighting condition—daylight or dark. It's engineered for shooters who need speed and simplicity, whether you're at the range, in competition, or carrying for defense.

What makes the FT Bullseye different is its hybrid illumination system. Fiber optic gathers ambient light during the day, giving you a bright aiming point when the sun's up. When darkness falls, premium-grade tritium takes over with self-illuminating glow that Meprolight guarantees for 12 years—no batteries to die, no switches to fiddle with. You get an illuminated dot surrounded by a bullseye circle that trains your eye toward the center naturally, supporting the kind of intuitive, reflex-speed shooting you need when it counts.

Installation is straightforward: the sight mounts to standard pistol dovetails and requires no front sight, so it works with most existing carry holsters without modification. It's the kind of uncompromising Israeli engineering Meprolight is known for—rugged, minimal, and built to work when everything else is falling apart.

Frequently Asked Questions

Will the FT Bullseye rear sight work with my existing pistol and holster?

The FT Bullseye mounts to standard pistol dovetails and doesn't require a front sight, so it fits most pistols and works with existing holsters. Check your pistol's dovetail specification to confirm compatibility, and verify that your current holster has clearance for a rear sight without a front sight pair.

How long does the tritium stay bright, and what happens when it runs out?

Meprolight guarantees 12 years of nighttime illumination from the tritium. After that period, the tritium will gradually dim, though some glow may persist beyond 12 years. The fiber optic component will continue to function in daylight indefinitely.

Does the FT Bullseye require batteries or a light source to work?

No. The fiber optic uses ambient light and requires no power source. The tritium is self-luminous and needs no batteries, switches, or external light. It's always ready and always on.
