The AmeriGlo XL Tall Optic-Compatible Sight Set (brand part number GL429) raises a Glock’s factory sight picture high enough to co-witness with a slide-mounted mini red dot or a suppressor. AmeriGlo pairs a black, serrated, wide front sight with a matching black notch flat rear sight, both cut to the XL Tall height so the irons stay usable as a fast back-up reference even with an optic mounted. It’s built to fit Glock Gen1-5 pistols and matches the Aimpoint Acro, Holosun 509T, and Steiner MPS optic footprints, so it drops right onto a slide already cut for one of those red dots.
