Meprolight Fiber-Tritium Bullseye Green Rear Sight for Springfield XD/XDM

The Meprolight Fiber-Tritium Bullseye Green Rear Sight for Springfield XD/XDM combines proven night-fighting technology with daylight-bright acquisition for shooters who demand reliability in low-light and bright conditions alike. This rear sight is engineered for law enforcement, military personnel, and defensive shooters who rely on their Springfield pistol as a primary duty or backup weapon. Meprolight's hybrid fiber-tritium design bridges the gap between traditional iron sights and modern combat optics, delivering consistent sight picture whether you're training on the range or responding to a critical incident.

The bullseye green rear sight utilizes a combination of light-gathering fiber optics and self-illuminating tritium, allowing the sight to remain visible in complete darkness without battery dependency while maintaining exceptional brightness in daylight. The fiber-optic element captures ambient light to produce a vivid green aiming point under normal conditions, while the tritium phosphate core activates in low-light scenarios—a critical advantage during tactical operations or low-light defensive scenarios. The sight's design geometry maintains the familiar sight picture shooters expect from XD/XDM platforms, ensuring rapid target acquisition and minimal training curve for operators transitioning from standard iron sights.

This rear sight is purpose-built for Springfield XD and XDM-series pistols and installs in seconds without gunsmithing or special tools. Tactical professionals running duty or competition loads benefit from the repeatable sight picture and rapid target engagement capability across all lighting conditions. The compact profile and durable construction withstand harsh handling, recoil cycling, and extended field use—making it an ideal upgrade for shooters seeking enhanced low-light performance while maintaining iron-sight reliability and simplicity.
