The AmeriGlo 5XL Optic Compatible Tritium Front Sight Set for Glock, Green with Black Outline (AmeriGlo part no. GL-812) is a tall front and rear sight pair made to co-witness with a slide-mounted red dot. AmeriGlo builds the front with a green tritium lamp ringed in black, set at a .407 height, and pairs it with a flat black rear that stands .507 overall. The tall 5XL sizing lifts the iron sights up into the optic’s window so they serve as a true back-up if the dot fails. The set fits all Glock models, including MOS slides.

A red dot on the slide is only one part of a good setup; the irons behind it should be ready to take over. This set gives a Glock a lit tritium front and a clean black rear at the height an optic needs. Order it from our Lubbock, Texas gun shop and see more gun sights while you are here.
