Description
The AmeriGlo GL682 is a 5XL tall sight set built for Glock owners running a slide-mounted red dot or a suppressor. That extra height lifts your iron sights up into the optic window so you get a proper co-witness, giving you a backup aiming reference that lines up with your dot instead of hiding below it. Depending on your slide and optic footprint, folks tend to land somewhere between a lower 1/3 and near-absolute co-witness with a setup like this, which is exactly the sweet spot most people want when pairing irons with a Trijicon RMR, Vortex Venom, Holosun, or Burris FastFire.
The front sight carries a Swiss-made green tritium insert wrapped in a bright LumiGreen outline ring, so it grabs your eye fast in daylight and glows on its own once the sun goes down. The rear is a flat black backup with no distracting dots, which is a deliberate choice. When you've got a red dot up top, a busy rear sight competes with the reticle for your attention. Keeping it blacked out lets the dot do its job and keeps your focus where it belongs.
What the GL682 Fits
This set covers a huge chunk of the Glock family. It works across Gen 1 through Gen 5 models including MOS slides, and the only guns left out are the smaller 42 and 43 (and typically 43X and 48). The front measures .407" and the rear .507", which is that 5XL height that clears most common suppressors on a threaded barrel and stacks up well behind popular optics.
Installing the AmeriGlo GL682
These go in much like factory Glock sights, though the fit can run snug. A proper sight pusher tool makes the job painless, and it's not unusual to add a touch of thread locker on the front screw for peace of mind. If you're not comfortable pressing your own sights, any gunsmith can knock this out in a few minutes. The steel construction holds zero round after round, which is why AmeriGlo has earned a following with duty and everyday carry crowds alike.

Frequently Asked Questions
Will the AmeriGlo GL682 co-witness with my red dot?
That's exactly what this 5XL set is built for. Depending on your specific slide and optic footprint, most owners land somewhere between a lower 1/3 and near-absolute co-witness with dots like the Trijicon RMR, Vortex Venom, Holosun, and Burris FastFire. It's a good idea to measure your optic's window height before ordering if you want a precise result.
Which Glocks does the GL682 fit?
It covers the large majority of the Glock lineup across Gen 1 through Gen 5, including MOS slides. The main exceptions are the smaller frames like the 42 and 43, and typically the 43X and 48 as well. If you're running a full-size or compact Glock, you're almost certainly covered.
Why is the rear sight flat black instead of having dots?
When you've got a red dot mounted, a rear sight with glowing dots competes with your reticle for attention. The blacked-out rear keeps your eye locked on the front tritium and the dot itself, which is what you want in a defensive or competition setup. It's a deliberate design choice, not a downgrade.
Is the GL682 hard to install?
It installs much like factory Glock sights, though the fit can run tight. A quality sight pusher tool makes the swap smooth, and some owners add a small drop of thread locker to the front screw for extra security. If you'd rather not press your own, any gunsmith can handle it quickly.
