Optics-Ready Lower 1/3 Co-Witness Night Sights

Night Fision designed this sight set specifically for optics-ready Glock pistols. The lower 1/3 co-witness height allows the iron sights to sit just below the optic’s window, providing a clear field of view through the red dot while still offering a reliable backup sighting system. The stealth rear sight features a completely blacked-out design with no white outline, reducing visual distraction when the optic is in use. The front sight is equipped with a bright yellow tritium insert, offering excellent visibility in low light without overpowering the optic’s reticle.

Why Choose Night Fision Optics Ready Stealth Sights?

Night Fision has earned a strong reputation for producing some of the brightest and most reliable tritium night sights on the market. This Optics Ready Stealth set is specifically engineered for modern shooters who run red dot sights on their Glock pistols. The lower 1/3 co-witness height is the preferred setup for most competitive and defensive shooters because it keeps the iron sights out of the way of the optic while still providing a fast and reliable backup sighting system. The blacked-out rear sight eliminates visual clutter, allowing the shooter to focus entirely on the red dot. When the optic is not in use or fails, the bright yellow tritium front sight provides an immediate and highly visible aiming point in any lighting condition.

Ideal Applications

This sight set is perfect for Glock owners who have mounted or plan to mount a red dot optic. It is especially popular among competitive shooters using the Holosun SRO or 507C, as well as those running Trijicon RMR or Aimpoint ACRO optics. Concealed carry users who want the speed of a red dot with the security of backup iron sights will appreciate the lower 1/3 co-witness design. Tactical professionals and law enforcement officers also favor this configuration for its balance of speed and reliability. The stealth rear sight makes this set particularly well-suited for shooters who want a clean, modern look when using an optic.

Build Quality and Performance

Night Fision sights are manufactured using precision CNC machining and high-quality steel for exceptional durability and consistency. Each tritium vial is carefully installed and sealed to ensure long-lasting brightness. The stealth blacked-out rear sight is designed to minimize glare and visual distraction, while the front sight’s yellow tritium insert offers one of the brightest and most visible aiming points available. The sights are built to withstand the rigors of daily carry, competition, and professional use. Night Fision’s attention to detail and commitment to quality make this sight set a top choice for Glock owners who demand both performance and reliability from their iron sights.
