The AmeriGlo GL491 optic compatible 3XL tall sight set for Glock brings precision backup iron sights to your MOS-slide pistol, especially when you're running a modern red dot. These sights were engineered for shooters who want dependable iron sights that coexist with optics like the Trijicon RMR, SRO, or Holosun 407/507/508T. The taller 3XL profile clears most common pistol-mounted optics, so you get true co-witness capability without compromise. Whether you're training at the range, running a defensive setup, or competing, AmeriGlo backs this set with quality construction designed to handle real use.
What separates this sight set from budget alternatives is the tritium front sight paired with a flat black rear. The green tritium front carries a white outline, making it easy to track in low light or bright sun—a genuine advantage in defensive scenarios where speed matters. The rear sight's clean black finish minimizes glare and keeps your focus on the target. Both sights are built to exacting specs so they install and function reliably on Glock MOS slides without aftermarket adapters or gunsmithing.
AmeriGlo has built a reputation in the aftermarket sight space by understanding what working shooters need: sights that don't fail, adjust intuitively, and play nice with modern pistol setups. This GL491 set carries that tradition forward for the Glock shooter who wants tactical-grade irons to back up an optic.

| Model | GL491 |
| Sight Height | 3XL Tall |

Yes. The GL491 is built for Glock MOS pistols and the 3XL height is designed to co-witness with Trijicon RMR, SRO, Holosun 407, 507, and 508T optics, so your backup irons clear the optic and function as true co-witness sights.
Tritium fronts glow in low-light conditions without batteries or charging—useful for home defense, low-light ranges, or any scenario where ambient light is dim. The white outline helps you pick up the sight picture quickly in daylight too.
These sights are designed to install on Glock MOS slides without additional adapters or modifications. Install and use instructions should accompany the set; verify fitment for your specific Glock model before installation.
Yes. Although designed as backup irons for optic-equipped pistols, you can run these sights standalone on your Glock MOS if you choose.
