Designed to work with optics, not suppressors, the Night Fision Optics Ready sight blade heights offer the perfect co-witness tailored to the shooter's preference. Serrated for low-glare, you'll never know they're there until you need them. Housed in durable, CNC-machined steel sight bodies, all Night Fision Fiber Sights carry fine serrations on their face for a low-glare surface. Available in multiple rod colors, a generous amount of the fiber rod is exposed for maximum brightness. Optics Ready sights are designed to be paired with pistol optics and offer approximately a lower 1/3 co-witness. FeaturesSerrated for low-glareLower 1/3 co-witnessSteel sight body
