XS Sights R3D 2.0 night sights combine tritium lamps in both front and rear with a high-contrast glow dot design and photoluminescent technology that absorbs ambient light for visibility in low-light conditions. The rear sight features a wide 0.170″ notch with serrations and an anti-reflective lens to minimize glare, while a corrosion-resistant Black Nitride finish protects against long-term wear.
The serrated rear sight is equipped with tritium lamps to support sight alignment in any lighting condition and includes a ledge design to facilitate one-handed manipulations. The wide notch provides enhanced visibility on either side of the front sight post, enabling faster sight alignment in poor lighting.
The green front sight is fitted with photoluminescent Ember Glow Dot Technology that absorbs ambient light and glows in low-light settings. The front tritium lamp charges the Ember dot, producing a brighter glow at the front sight than at the rear at all times to maintain downrange focus. R3D sights are CNC machined from solid steel bar stock and proudly manufactured in Fort Worth, TX, designed to fit Sig Sauer P320, P365, P225, P226, P228, P229, and other models.
