Meprolight USA FT Bullseye Rear Sight - Black | Green Tritium/Fiber Optic (631023108)

The Meprolight USA FT Bullseye Rear Sight is a standalone rear sight designed to work without a traditional front sight, combining fiber optic and tritium illumination in a single compact unit. Built for shooters who want a fast, reliable aiming system that functions in any light condition—bright sunlight, low light, or complete darkness—this rear sight puts you on target day or night without batteries or electronics to maintain. The design centers around a simple aiming principle: place the illuminated dot in the circle reticle and you're ready to fire. It's built for practical shooting, defensive carry, and training where speed and confidence matter.

The FT Bullseye's low-profile form factor won't snag clothing during draws or re-holstering, and its compact footprint works with standard holster designs. The combination of green tritium and fiber optic technology means the sight glows passively in low light (tritium) and brightens in daylight (fiber optic), giving you a visible aiming reference whether you're at the range, in the field, or in a self-defense scenario. Because there's no front sight to align, target acquisition is straightforward—just center and press.

This is purpose-built for shooters tired of traditional two-sight systems and looking for a simpler, faster alternative. If you carry daily, train regularly, or shoot competition, the bullseye sight eliminates sight picture complexity while maintaining the precision you need.

Frequently Asked Questions
