Meprolight FT Bullseye Green Front Sight for Glock Models 17, 19, 20, 21, 22, 23, 24, 26, 29, 30, 34, 35, 36

The Meprolight FT Bullseye green front sight for Glock is a compact optical sight engineered to replace your factory front post with a fast-acquiring aiming solution that works in any light without batteries or electronics. Meprolight's patented optical design delivers an illuminated dot-and-circle bullseye reticle that combines fiber-optic brightness for daylight shooting with self-illuminating tritium for low-light and night use. If you're running a Glock 17, 19, 20, 21, 22, 23, 24, 26, 29, 30, 34, 35, or 36, this sight installs directly into your existing dovetail and is small enough to work with most stock holsters—no gunsmith work or slide cuts required.

Shooters often struggle with transition speed between aiming point and target, especially in mixed lighting. The Meprolight FT Bullseye addresses that with an intuitive aim point that lets your eye naturally settle on the illuminated center. The fiber-optic gathers ambient light in bright conditions, so you get a vivid sight picture during the day; when the sun sets, the tritium takes over with guaranteed illumination for 12 years. Since there are no batteries to die, no switches to fumble, and no electronics to fail, the sight is always ready—in your nightstand gun, your carry piece, or your training rig.

This is a serious upgrade for shooters who want faster, more intuitive sight acquisition without the complexity, cost, or slide modifications of a mini-reflex optic. The small profile and dovetail mount make it a practical choice for duty, carry, home defense, and recreational shooting where reliability and speed matter more than bells and whistles.

Frequently Asked Questions

Will the Meprolight FT Bullseye fit my Glock and work with my holster?

Yes, this sight is designed for Glock models 17, 19, 20, 21, 22, 23, 24, 26, 29, 30, 34, 35, and 36. It mounts directly into your existing dovetail with no slide modification. Because of its compact, low-profile design, it's compatible with most stock and aftermarket holsters—though it's always a good idea to verify fit with your specific holster before carrying.

How does the illumination work without batteries?

The FT Bullseye uses a dual-source system: during the day, a fiber-optic element gathers ambient light to create a bright aiming point. At night or in low-light conditions, self-illuminating tritium takes over automatically. Since there are no batteries, switches, or electronics, the sight requires no maintenance and is always ready to use.

How long will the tritium stay bright?

Meprolight guarantees tritium illumination for 12 years from the date of manufacture. After that period, the sight will continue to function and gather light via the fiber-optic element, but the nighttime glow will gradually fade.

Is any installation work required?

No—the sight installs directly into your existing Glock dovetail. No gunsmith, slide cuts, or special tools are needed. Installation is straightforward and fits most existing holsters.
