XS Sights R3D 2.0 Standard Height Night Sights – Green

The XS Sights R3D 2.0 Standard Height Night Sights are a tritium-equipped sight set designed for Glock pistols. They combine tritium and photoluminescent elements to aid low-light sighting while a serrated, blacked-out rear reduces glare and visual distraction. The R3D 2.0 improves installation by requiring substantially less force than the prior generation and carries a corrosion-resistant black nitride finish for longevity. These sights are engineered for everyday carry, duty, and general-purpose use where reliable low-light performance is required.
