Night Fision Optics Ready Stealth Series Sights Features The Night Fision Optics Ready Stealth Series Sights use a domed lens that collimates the tritium rays inside the front sight for a sharper brighter sight picture in low light. Unlike traditional tritium sights that rely on aluminum sleeves and painted-on white rings Night Fision s patented injection molded sleeve called The Perfect Dot holds the tritium vial securely while producing a brighter more durable ring visible day and night. The front sight carries a yellow fluorescent ring for fast daytime acquisition paired with a plain black rear sight for a clean distraction-free picture downrange. Both sights are CNC machined from high quality steel for long-term durability. A black nitride coating is applied over the steel to improve wear resistance and guard against corrosion through hard use. These sights are purpose built to fit the Glock 19 45 and 47 when running an Aimpoint COA mounted optic allowing the irons to co-witness properly with the red dot. This fitment makes them a natural choice for duty and competition shooters who need reliable backup irons alongside their optic. For Glock owners seeking a durable optics ready sight set the Night Fision Stealth Series Sights are available for sale at GrabAGun.
