XS Sights R3D 2.0 Suppressor Height Tritium Night Sight
Sig Sauer Compatible - Orange/Tritium

Experience total confidence in every lighting condition with the XS Sights R3D 2.0 Tritium Night Sights, engineered for shooters who demand speed, durability, and absolute clarity. Whether you're carrying daily, training hard, or relying on your firearm for duty use, these suppressor‑height sights deliver a brighter, stronger, and faster sight picture—day or night.

The upgraded dual‑illumination front sight combines a self‑powered green tritium lamp with a high‑contrast orange Ember Glow Dot that supercharges visibility by absorbing ambient light and glowing brilliantly in low‑light environments. Paired with a serrated, anti‑reflective rear sight featuring enhanced green tritium lamps and black PVC rings for crisp definition, the R3D 2.0 drives your focus forward for rapid, instinctive alignment.

Built from CNC‑machined steel and finished in ultra‑durable Black Nitride, these sights are designed to withstand years of EDC abuse while maintaining a clean, sharp sight picture. With improved dovetail geometry requiring 50% less installation force, the R3D 2.0 is as user‑friendly as it is rugged.
