Ameriglo GL511 Optic Compatible Sight Set for Glock - XL Tall Green Tritium Orange Outline Front / Flat Black Rear

The Ameriglo GL511 is an Optic Compatible (suppressor-height) iron sight set engineered specifically for Glock pistols. Built around a rugged steel construction with a black finish, this XL Tall (XLT) configuration is designed to deliver an elevated co-witness sight picture when paired with a slide-mounted red dot optic, while also serving as reliable backup iron sights on any optic-cut Glock slide.

The front sight features a self-illuminating green tritium lamp wrapped in a high-visibility orange photoluminescent outline at .315" tall, giving the shooter a fast, intuitive sight picture in any lighting condition - from bright daylight to low-light and complete darkness. The rear sight is a low-glare flat black square notch at .394" tall, providing a clean sight picture that won't compete with a mounted red dot and clears most common suppressors. The taller-than-standard profile keeps the iron sights visible above the red dot housing for a true co-witness aiming solution.

Installation is straightforward using the factory Glock dovetail mounts, and the GL511 fits Glock Gen 1-5 standard-frame pistols (excludes the slim-frame 42, 43, and 48, which use the GL351). The tritium lamps are self-illuminating and require no batteries or switches, so your sights are always ready. Whether you run a slide-mounted red dot and need co-witness backup sights, or just want a daylight-capable, suppressor-friendly iron-sight upgrade, the Ameriglo GL511 XLT delivers reliable aiming for defensive, duty, or everyday carry use.
