Meprolight FT Bullseye for Mark IV

• Single-sight bullseye aiming system: The FT Bullseye replaces the usual front-and-rear sight picture with one compact aiming reference, helping speed up sight acquisition on a compatible Ruger Mark III or Mark IV pistol.
• Fiber optic and tritium illumination: Daylight brightness comes from fiber optics, while tritium keeps the aiming point visible in low light and darkness without relying on batteries.
• Fixed, low-profile construction: The fixed design keeps the sight simple and durable, with no controls to adjust during use and less bulk than a slide-mounted optic.
• Aluminium housing: The metal body gives the sight a solid structure for regular range use and carry, while keeping the overall setup compact.
• Battery-free operation: Because the FT Bullseye works without electronics or batteries, it is always ready and avoids the maintenance routine of powered pistol optics.

About the Meprolight FT Bullseye Series

Meprolight FT Bullseye is a handgun-sight family in Meprolight’s current lineup that brings a different approach to pistol aiming. Rather than using a conventional notch-and-post arrangement, the series is built around a bullseye-style sight picture that combines fast alignment with a very compact footprint. This makes the series especially relevant for defensive pistols, concealed-carry handguns, and shooters who want quicker target acquisition without moving to a full electronic red dot.

A defining trait of the FT Bullseye series is its fiber optic daytime illumination paired with tritium for low-light use. That combination gives the sight a visible aiming reference across changing light conditions while remaining completely battery-free. The family includes both front-sight and rear-sight versions, depending on the host pistol and intended setup. Across the range, the design philosophy stays consistent: keep the sight compact, self-illuminated, and simple to use under stress. For shooters who want a pistol sight that sits lower than a miniature reflex sight and avoids batteries altogether, the FT Bullseye line fills a distinct place in modern handgun optics.

About the Meprolight FT Bullseye for Mark IV

The Meprolight FT Bullseye for Mark IV is configured for Ruger Mark III / Mark IV pistols and is built around a single, enclosed aiming reference rather than a separate front and rear sight picture. In practice, that means the shooter centers the illuminated bullseye instead of aligning multiple elements, which can make the sight picture feel faster and more intuitive, especially during rapid strings on the range or when transitioning between targets.

This model uses fiber optics for daytime visibility and tritium illumination for low-light conditions, so the sight remains usable across a wide range of lighting without switches or batteries. That matters on a rimfire pistol such as the Mark IV, where a simple, always-on sighting system suits training, informal target shooting, and general field use. The fixed sight adjustment also keeps the design straightforward, with no exposed controls to snag or shift in routine handling.

The aluminium housing helps keep the sight compact while providing a more robust structure than a polymer body. Its low-profile form preserves the clean handling characteristics of the pistol and offers an alternative to bulkier slide- or receiver-mounted optics. For shooters who want a battery-free handgun sight with a fast visual reference, this FT Bullseye model gives the Ruger Mark platform a modern sighting concept in a compact format.
