Description
The AmeriGlo GL482 is a 5XL tall, optic-compatible sight set made for Glock owners running a red dot, a suppressor, or both. It pairs a green tritium front dot ringed in a bright white outline with a flat black rear, so your eye snaps to the front sight fast while the plain rear keeps things clean and glare-free. At .407 inches up front and .507 inches at the rear, these sit high enough to poke up through most pistol optic windows for that lower 1/3 co-witness a lot of folks are after.
What the GL482 Does on an Optic-Ready Glock
The whole point of a suppressor-height set like this is elevation. Standard Glock irons sit too low to be seen through an optic window, which leaves you with no backup if your dot ever craps out or the battery dies. Mount these and you get a usable iron sight picture underneath your red dot, plus enough clearance to clear most cans on a threaded barrel. The tritium up front means it works in the dark just as well as it does in daylight, and the white outline gives you a crisp aiming reference on the range even before your eyes adjust.
Fit and Build on the AmeriGlo GL482
These are CNC-machined from steel rather than the polymer that ships on a lot of Glocks, so they hold up to recoil and years of carry. The set is cut for standard Glock dovetails and drops in with a sight pusher or a Glock front sight tool, no permanent modifications needed. AmeriGlo lists the GL482 as fitting all Gen 1 through Gen 5 Glocks except the 42 and 43, and it plays nicely with MOS slides and popular footprints like the Burris Fastfire and Vortex Venom. Exact co-witness height will depend on your specific optic and mounting plate, so it's worth checking your optic's window-bottom measurement before you commit.

Frequently Asked Questions
Will the GL482 co-witness with my red dot?
This 5XL tall set is built to give you a lower 1/3 co-witness with most slide-mounted pistol optics, meaning the irons sit in the lower portion of the window with your dot above them. Exact positioning depends on your specific optic and whether you're running an MOS plate or a milled slide. It's smart to check your optic's window-bottom-above-slide height against the .407 inch front and .507 inch rear before ordering.
Which Glocks does the AmeriGlo GL482 fit?
AmeriGlo lists the GL482 as compatible with all Glock Gen 1 through Gen 5 models, with the exception of the 42 and 43. It works with standard Glock dovetail cuts as well as MOS slides. The smaller-framed 43X and 48 use different sight dimensions, so those aren't covered by this set.
Do these work as backup sights if my optic fails?
That's exactly what they're designed for. Because the sights sit tall enough to project into the optic window, you keep a usable iron sight picture if your red dot's battery dies or the dot shifts. The green tritium front dot keeps you in the fight in low light, not just on a bright range.
How hard is the GL482 to install?
Installation is on par with swapping factory Glock sights. The rear goes in with a sight pusher and the front mounts with a Glock front sight tool, with no permanent modifications to your slide. If you're not comfortable pressing sights yourself, most gunsmiths or a local shop can knock it out in a few minutes.
