The AmeriGlo GL691 sight set delivers co-witness capability for Glock pistols equipped with red dot optics while maintaining reliable backup iron sight performance. This 3XL tall configuration provides proper sight picture alignment when shooting through most popular micro red dot sights.
What Makes This Different
The GL691 features AmeriGlo's Lumigreen tritium insert technology, providing consistent illumination for 12+ years without batteries or external light sources. Unlike standard height sights, the 3XL tall front sight measures .394" in height, specifically engineered to co-witness with mounted optics.
