The XS R3D Suppressor-Height Night Sight in Green (XS Sights part no. GL-R021P-6G) is a tritium sight set built for Glock pistols running a suppressor or a slide-mounted red dot. The extra sight height clears the bore line of a suppressor and lets you co-witness through most micro red dots, so you keep a usable iron-sight picture no matter what is mounted up front. Both the front and rear sights are steel with tritium inserts, giving you a bright, glowing aiming point in low light and a rear sight edge shaped to aid one-handed slide manipulations. It is a direct fit for a wide range of Glock generations and models, making it an easy upgrade for duty, defense, or suppressor-ready builds.
