Night Fision Optics Ready Stealth Series Sights Features The Night Fision Stealth Series Sights are CNC machined from high quality steel giving them the strength and precision needed to maintain accurate point of impact over years of use on a duty or carry Glock 19 45 or 47. The blank front and rear sight design is intended for shooters running an Aimpoint COA mounted optic providing a clean distraction-free co-witness picture rather than competing dots or inserts. A black nitride coating is applied to improve wear and corrosion resistance helping the sights resist the effects of holster friction sweat and daily carry conditions. This finish keeps the sights functioning reliably long after less durable coatings would begin to degrade. Night Fision built its reputation on moving away from the traditional aluminum sleeve and painted-on white ring tritium sight design common across the industry. Instead their patented injection molded sleeve design holds tritium vials securely in place while creating a brighter more durable ring the company calls The Perfect Dot improving visibility in low light. While this particular sight set is blank to suit optic-equipped Glocks the same rugged construction and finish techniques apply throughout the Stealth Series line. These Night Fision sights are available for sale at GrabAGun for Glock 19/45/47 owners running a slide-mounted optic who want a durable low-profile set of backup sights.
