XS Sights R3D 2.0 Night Sight Set – S&W M&P Shield (Optics Ready) – Green Front

The XS R3D 2.0 night sight set is designed specifically for optics-ready S&W M&P Shield pistols, providing a lower 1/3 co-witness with factory-cut slides. The green tritium front sight is surrounded by a high-contrast photoluminescent glow ring that charges in ambient light, offering fast target acquisition in any lighting condition. The blacked-out rear notch eliminates distractions and drives focus to the front sight.

This set is machined from steel and installs using a standard sight pusher or drift punch. The front sight is secured with a set screw. Compatible with M&P Shield models that have been milled for optics from the factory. Tritium has a usable lifespan of approximately 12-15 years from manufacture date.
