The AmeriGlo Optic Compatible Sight Set for the Glock Gen 5 Standard Width A-Cut with front and rear tritium (AmeriGlo part no. AC-813) upgrades both the front and rear sight with green tritium inserts, cut for a precise, elevated co-witness with a slide-mounted red dot. AmeriGlo designed this Optic Compatible line to serve as a reliable backup sight system that lines up correctly with the optic’s window instead of sitting too low or too high. Having tritium in both sights, rather than just the front, gives a fully-illuminated sight picture for true low-light backup use if the optic ever fails.
