XS Sights’ second-generation R3D 2.0 night sights deliver increased brightness and strength compared to the original design. Installation is simplified with a system requiring 50% less force than previous versions. Built for the demands of everyday carry, these sights are engineered to endure years of regular use and handling. The serrated, blacked-out rear sight directs your focus downrange, while the dual-illuminated tritium photoluminescent front sight ensures visibility across lighting conditions. The R3D 2.0 represents the brightest notch and post option available, enabling fast and accurate shooting whether in daylight or low-light environments.
This set is designed for the Glock 21 and features suppressor height sizing for optimal sight picture with suppressed firearms.
