Specifically designed for the Glock G43X and G48 models, these sights are derived from the highly regarded AmeriGlo GL-527. The front sight has a height of 0.45 inches, while the rear sight measures 0.554 inches in height. This sight set provides a lower 1/3 co-witness with the Trijicon RMRcc when paired with our OPF-G43X/43, RMRcc on Glock's G43X and G48 models.
