Ameriglo GL691 Optic Compatible Sight Set for Glock 3XL Tall - Green Tritium Lumigreen Front / Flat Black Rear

The Ameriglo GL691 is an optic-compatible, suppressor-height tritium night sight set built specifically for Glock pistols. Designed to deliver a proper co-witness through slide-mounted red dot optics, the GL691 pairs a tall, easy-to-index front blade with a low-glare rear so your iron-sight backup stays functional in any lighting condition.

Up front, the sight sits at a 3XL Tall height with a .365" blade profile and features a green tritium vial wrapped in a bright Lumigreen outline for fast, intuitive low-light target acquisition. The matching rear sight is a flat-faced .451" blade finished in non-reflective flat black to minimize glare and keep the shooter's eye on the front sight picture.

Both elements are housed in a rugged steel frame with a tough black finish. The GL691 fits all Glock Gen 1-5 pistols (excluding the 42, 43, and 48), including standard and MOS slide configurations, making it a versatile iron-sight upgrade for pistols running a slide-mounted red dot.
