The Meprolight Fiber-Tritium Bullseye Green Rear Sight for S&W M&P Shield, Shield Plus, and 2.0 combines fiber-optic and tritium illumination into a single low-profile night sight designed for rapid target acquisition in all lighting conditions. This rear sight delivers the intuitive single-point-of-focus aiming geometry that operators familiar with red dot systems expect, without requiring batteries or electronics.
The dual-illumination design pairs premium-grade tritium for low-light and blackout scenarios with fiber-optic collection for daylight use. The Bullseye sight's green tritium insert and fiber core are engineered for reliable performance through heavy recoil and sustained-fire training cycles. The low-profile mounting geometry integrates seamlessly with M&P Shield platform ergonomics and maintains compatibility with standard holsters designed for these models. This design eliminates the need for manual brightness adjustment while maintaining a clean, snag-free profile suitable for concealed carry and duty use.
The Meprolight Fiber-Tritium rear sight suits operators, law enforcement, and civilian carriers who prioritize fast sight picture acquisition during critical-response scenarios. Users seeking dependable night sight capability for M&P Shield platforms—from standard Shield through Shield Plus and 2.0 generations—will find this rear sight addresses the limitations of factory sights while preserving the defensive-carry profile these models are engineered for. The green tritium option provides enhanced visibility against common tactical backgrounds compared to traditional white-dot configurations.
Modern night sight technology serves a critical role in self-defense and duty carry, where engagement scenarios extend beyond daylight hours. The M&P Shield family remains one of the most widely deployed compact defensive platforms, and upgrading the rear sight to tritium-fiber technology directly improves shooting precision in variable lighting without adding weight or bulk. This rear sight is compatible with M&P Shield, Shield Plus, and Shield 2.0 models but excludes Shield EZ variants.
