The AmeriGlo GL691 Optic Compatible Sight Set for Glock delivers backup iron sights purpose-built for shooters running optics on MOS-platform Glocks. If you're mounting a Trijicon RMR, SRO, or Holosun 407/507/508T on your pistol, these sights are engineered to coexist with your optic—and work hard when you need them most. The 3XL tall front sight pairs a tritium element with a lumigreen outline for fast target acquisition in low light, while the flat black rear keeps your sight picture clean and your transitions smooth.
AmeriGlo sights earned their reputation by doing one job exceptionally well: getting you on target fast, day or night. Whether you're training at the range, heading to a match, or carrying for personal protection, having quality backup sights you trust frees your head to focus on fundamentals. The tritium/lumigreen front works without batteries, glows reliably in darkness, and handles the recoil and wear of serious use. The flat black rear is simple, proven, and won't catch light when you don't want it to.
These sights fit Glock MOS models configured with your compatible optic platform—no gunsmithing required. Installation is straightforward if you're comfortable with basic sight changes; if not, your local gunsmith can have you running in minutes. They're built tough, perform consistently, and won't nickel-and-dime you with surprises downrange.

Frequently Asked Questions
Will these sights work with my Glock and optic setup?
The AmeriGlo GL691 is engineered for Glock MOS pistols paired with Trijicon RMR, SRO, or Holosun 407/507/508T optics. Verify your Glock is MOS-cut and your optic matches one of these platforms before ordering.
Do I need batteries for the tritium sights?
No. Tritium is self-illuminating and requires no batteries, charging, or external power source. It glows for years without maintenance.
Can I use these as primary sights or only as backups?
These sights are designed to work alongside your mounted optic. They serve as backup iron sights and allow for co-witnessing when your optic is mounted on a compatible MOS slide.
