AmeriGlo 2XL Glock Sights – Suppressor & Optic Ready
AmeriGlo 2XL Glock Sights – Built for Co-Witness & Suppressor-Ready Setups
If you’re running a red dot or suppressor on your Glock, your sights need to keep up. The AmeriGlo 2XL Sight Set (GL-810) is designed to give you reliable backup aiming — tall enough for co-witnessing through optics and clearing most suppressors, without sacrificing speed or visibility.
This set includes a tritium-powered front sight (.350") and a plain black rear (.429"), offering a clean, fast sight picture in any light condition. Whether you carry daily, train often, or need serious duty-grade gear, the AmeriGlo 2XL is trusted by shooters who don’t settle.
🔧 Optimized for Glock MOS & Optic-Cut Slides
Perfectly aligned for lower 1/3 co-witness, the 2XL series sits high enough to clear red dots like the Trijicon RMR, Holosun 507C, and Vortex Viper — with no modification required. It fits Glock factory MOS slides and most aftermarket optic cuts, making it a drop-in solution for backup aiming or primary use.

🔍 Why Choose AmeriGlo 2XL?
Unlike standard Glock sights, the 2XL set is purpose-built for optics and suppressors. Standard-height sights are invisible behind most red dots. The XL line gets close, but only the 2XL provides a consistent lower 1/3 co-witness that works with today’s most popular optics and slide setups.
If you’ve been searching for the “just right” sight height for Glock MOS — this is it.
