The XS Sights R2D 2.0 Suppressor Height Night Sights for Glock Green Front with Black Rear deliver a practical, high-contrast sight picture for fast target acquisition and improved accuracy in dim conditions, combining tritium front and rear with a high-contrast glow dot and a photoluminescent glow dot that absorbs ambient light to remain visible in low light. The wide notch rear with serrations and an anti-reflective lens, paired with a traditional 3-dot tritium notch and post sight picture, provides reliable alignment across a range of shooting scenarios, while the corrosion-resistant Black Nitride finish ensures durability in harsh environments. These suppressor-height sights are compatible with Glock Gen 15, including MOS models, and are proudly manufactured in Fort Worth, TX, making them a solid choice for duty, competition, or personal defense applications. Designed to fit Glock models such as 17/17L/19/22/23/24/26/27/33/34/35/38/39, the R2D 2.0 offers a robust combination of visibility, ruggedness, and fitment that supports rapid sight acquisition and precise shot placement when time and lighting are critical.
