Optimize your Glock for fast target acquisition and reliable low‑light performance with the AmeriGlo Optic-Compatible XL Tall sight set. Designed for co‑witnessing with pistol‑mounted micro red dots and for use with suppressors, these steel, optic‑compatible sights provide a taller sight plane, high‑visibility tritium illumination, and precise front/rear geometry for consistent sighting. Compatible with most Glock models (excludes 42, 43, 48) and MOS platforms, these sights are built to industry standards and tuned for rapid, intuitive aiming whether you run an Aimpoint Acro, Holosun 509T, Steiner MPS or comparable micro red dot.
