XS Sights R3D Night Sights: Precision Low-Light Shooting

The XS Sights R3D represents a thoughtful approach to night sight design, combining proven tritium technology with modern photoluminescent innovation. These sights deliver reliable performance across the full spectrum of shooting conditions, from bright daylight to complete darkness.

Key Features

Tritium 3-Dot Design

• Traditional notch and post sight picture for intuitive aiming
• Brighter tritium vial in front sight for proper focus and alignment
• Two rear tritium vials provide sight alignment without overwhelming the front sight
• Anti-reflective rear lens reduces glare and improves contrast

Glow Dot Technology

• Proprietary photoluminescent orange ring absorbs ambient light
• Glows reliably in low-light and no-light conditions
• Orange provides superior contrast in bright daylight while maintaining visibility after dark
• Self-charging design: tritium light slightly energizes the Glow Dot for enhanced brightness

Suppressor-Height Configuration

• Designed for co-witness with Trijicon RMR, Holosun 507C series, and Vortex Viper optics
• Maintains sight picture when red dot is mounted on factory MOS slide
• Allows seamless transition between iron sights and optics

Practical Construction

• CNC machined steel for durability and reliability
• Front blade width: 0.145 inches for enhanced visibility
• Rear notch width: 0.170 inches for improved front sight focus
• Rear sight ledge enables one-handed slide manipulation
• Compatible with standard holster options

Installation and Warranty

Installation requires a sight pusher tool or hammer and punch. Minor filing of the rear sight may be necessary for proper fit. XS Sights backs these sights with a 10-year warranty and 30-day satisfaction guarantee.
