Ameriglo GL8113R Classic Tritium Rear Sight for Glock Gen 1-5 - Green Tritium White Outline

The Ameriglo GL8113R is a Classic series tritium rear sight built for Glock pistols. Sold as a rear sight only, this unit is precision cut from steel with a low-glare black finish and installs as a direct factory replacement on the dovetail of the slide.

Featuring green tritium lamps in a 2-dot configuration with crisp white outlines, the GL8113R delivers an instant, easy-to-acquire sight picture in low-light and defensive shooting situations. The traditional .165 inch square notch and .276 inch sight height preserve a familiar sight picture and provide proper co-witness with standard-height front sights.

Designed to fit Glock Gen 1 through Gen 5 pistols, this rear sight is the ideal upgrade for shooters looking to add tritium night-sight capability to their handgun. Pair it with a matching Ameriglo tritium front sight to complete a low-light-ready sight system. Installation is straightforward using standard sight-pushing tools.
