The AmeriGlo Black Serrated Sight Set is a high-performance iron sight system specifically optimized for Glock Slimline MOS models like the 43X and 48. This "COA" (Co-witness Optic Compatible) set features a .220" or .240" tall serrated front post and a flat black square-notch rear, providing a clean, glare-free sight picture that clears the base of compact red dots such as the Holosun 407K/507K. These sights are precision-engineered to provide a Lower 1/3 co-witness on slimline MOS platforms, ensuring reliable backup aiming without obstructing the electronic reticle.
