XS Sights R3D 2.0 Suppressor Height Night Sights — Green Front

The XS Sights R3D 2.0 suppressor-height night sight set provides a high-visibility front post with matched tritium lamps front and rear for low-light sighting. The set pairs a wide photoluminescent Glow Dot front with a serrated, blacked rear that reduces glare and focuses the sight picture. Designed for suppressor-height applications and compatible with a range of Glock models, these sights include upgrades from the original R3D line such as brighter tritium and revised dovetail dimensions to aid installation. The BlackNitride finish and construction aim to resist wear and corrosion for extended everyday carry and duty use.
