The AmeriGlo Optic-Compatible XL Tall Sight Set for Glock (brand part number GL813) gives you a precise, elevated co-witness sight picture underneath a slide-mounted red dot optic or a suppressor, and it doubles as a reliable set of back-up iron sights if the optic ever fails. This XL Tall model uses a green tritium front sight with a black outline and a green tritium rear sight with a matching black outline, finished in black. It’s compatible with all Glock Gen 1-5 models except the G42, G43, and G48, and it fits the Glock MOS slide. The elevated geometry is also matched to co-witness with Aimpoint Acro, Holosun 509T, and Steiner MPS optic footprints.
