Brownells 3XL-Tall Tritium White Outline Sight Set for Glock GL-859 Brownells 3XL-Tall Sight Set Trit-Wht OL .365''F/Serrate .451''R for Glock GL-859 The Brownells 3XL-Tall Sight Set (GL-859) is a premium aftermarket sight upgrade designed for Glock pistols. This high-visibility set combines an extra-tall profile with a tritium-illuminated front sight, making it an excellent choice for shooters who run red dot optics and require reliable backup sights in all lighting conditions. Maximum Height for Optic Co-Witness These 3XL-Tall sights feature a .365-inch front sight and .451-inch rear sight, providing one of the tallest sight pictures available. This extreme height allows for a true lower 1/3 co-witness or absolute co-witness with most popular micro red dot optics mounted on Glock pistols, ensuring the iron sights remain fully usable as a backup aiming system. Tritium White Outline Front Sight The front sight is equipped with a self-illuminating tritium vial surrounded by a bright white outline. This combination provides excellent visibility in both bright daylight and low-light or no-light environments. The tritium glows continuously without batteries, offering a distinct aiming point when ambient light is limited. Serrated Rear Sight The rear sight features a serrated surface that helps reduce glare from sunlight and artificial lighting. This anti-glare treatment allows for faster and more precise sight alignment by minimizing distracting reflections, improving performance during daytime shooting while maintaining compatibility with the tall front sight.
