AmeriGlo’s GL452 sight set is an optic-compatible XL tall configuration designed to provide an elevated co-witness sight picture for slide-mounted red dot optics and to serve as a robust backup sighting solution. The front sight uses a green tritium insert with an orange outline for quick visual reference, while the rear sight uses a green tritium insert with a black outline and a black finish. The set is compatible with Glock Gen 1–5 models except 42, 43, and 48, and fits Glock MOS slides. It is compatible with Aimpoint Acro, Holosun 509T, and Steiner MPS footprints.
