The Night Fision Optics Ready Stealth Night Sight Set (brand part no. GLK-003-290-297-YGZX) is built specifically for the Glock 43X MOS, pairing a yellow front tritium vial with a black rear sight for a fast, high-contrast sight picture. Where most tritium sights rely on aluminum sleeves and painted-on white rings, Night Fision’s patented injection-molded sleeve design holds the tritium vials securely while creating a brighter, more durable ring they call The Perfect Dot for maximum visibility day or night. Each sight is CNC machined from high-quality steel and finished with a black nitride coating for wear and corrosion resistance, and a domed lens collimates the tritium rays for a sharper sight picture. Built in the USA with Swiss tritium, gunsmith installation is recommended.
