Meprolight FT Bullseye Rear Sight - Black | Green Tritium/Fiber Optic 631303108

The Meprolight FT Bullseye rear sight brings compact, battery-free illumination to your pistol without cluttering your sight picture. This optical rear sight uses a patented design that combines fiber-optic and tritium technology, giving you an illuminated dot and circle bullseye aiming point that works in bright daylight and pitch-black conditions alike. Unlike reflex sights, the FT Bullseye keeps the sight profile extremely low and small—no batteries, no switches, always ready when you are.

Installation is straightforward: the sight mounts directly onto existing pistol dovetails, and because it eliminates the need for a front sight, it typically fits inside most standard holsters without modification. That means faster draws and less fumbling with gear. The fiber-optic element gathers ambient light for crisp visibility in daylight shooting, while premium-grade tritium takes over in darkness or low-light scenarios, guaranteeing reliable nighttime illumination for 12 years.

Built for shooters who value simplicity and speed—whether you're training at the range, carrying for personal defense, or working through tactical courses—the FT Bullseye delivers intuitive target acquisition without the learning curve or dependency of electronic optics. No batteries means no dead batteries at a critical moment. No switches means one less thing to fumble. It's pure mechanical reliability in a sight package smaller than anything else in its class.

Frequently Asked Questions

Will the Meprolight FT Bullseye fit my pistol?

The sight mounts on standard pistol dovetails and fits most existing holsters since it eliminates the need for a front sight. Always verify your specific pistol's dovetail dimensions before purchase.

How does it work without batteries?

The FT Bullseye uses a fiber-optic element to capture ambient light during the day, creating a bright aiming point. At night or in darkness, premium-grade tritium—a self-illuminating radioactive isotope—provides instant illumination with zero external power.

How long will the tritium stay illuminated?

Meprolight guarantees tritium illumination for 12 years. After that, the tritium's brightness gradually diminishes over time, though the fiber-optic function remains usable in daylight.

Can I use this sight with my existing front sight?

The FT Bullseye is designed as a rear-only sight and eliminates the need for a front sight. Consult your pistol's manual or a qualified gunsmith to confirm compatibility before installation.
