The AmeriGlo XL Tall Optic-Compatible Sight Set (brand part no. GL191) is built to give a slide-mounted red dot a proper elevated co-witness sight picture while also clearing suppressor height, so the same sight set doubles as a reliable backup for either setup. The front sight uses a green tritium insert with a white outline for fast daylight acquisition and genuine low-light visibility, while the rear sight pairs a green tritium i-Dot insert with a black finish for a clean, high-contrast sight picture. AmeriGlo builds this XL Tall set to fit all Glock Gen 1-5 models, including MOS-cut slides, and cuts the footprint to match the Aimpoint Acro, Holosun 509T, and Steiner MPS optic mounting patterns. It’s a straightforward way to run co-witnessed irons with a slide-mounted optic or a suppressor without hunting for a separate tall sight set.
