Ameriglo 3Xl Tall Green Tritium White Outline Front Dot Rear Glock
$66.86
The AmeriGlo 3XL Tall Green Tritium night sights for Glock pistols are purpose-built backup sights and co-witness solutions for shooters running optics-ready slides with mounted red dots. Available as a complete set, these sights combine self-illuminating tritium with high-visibility outline geometry—green tritium dots paired with white outline on the front sight for rapid target acquisition in low light, and an i-Dot rear sight with a square notch for precise alignment. Whether you're building a duty gun, a nightstand defensive pistol, or a competition-ready setup with a slide-mounted optic, this AmeriGlo set keeps you combat-ready when daylight fades.
The tall 3XL profile positions your sights at proper co-witness height with common pistol-mounted optics, meaning your backup sights remain visible and usable even when your red dot is in use. All Glock generations—Gen 1 through Gen 5—accept this set, and it's compatible with Glock MOS (Modular Optics System) and other optics-ready Glock slides. The case-hardened finish resists wear on the range and in the field, while the tritium elements provide years of passive illumination without batteries or maintenance.
Built for shooters who demand reliability in the dark, AmeriGlo night sights eliminate the guesswork of acquiring your target when ambient light is low. Pair these with your favorite carry gun or duty platform and trust that you'll find your sights every time, even in a stressful moment.
