Night Fision Optics Ready Fiber Optic Sights Features The Night Fision Optics Ready Fiber Optic Sight Set is built with a serrated front sight housing a bright green fiber optic insert paired with a serrated black square rear sight for a fast low-glare sight picture. These Optics Ready Stealth height sights are designed specifically to work with slide-mounted red dot optics using the RMR 507C SR or ARCO footprints giving shooters the correct co-witness relationship between the irons and the dot. The .330 inch front and .353 inch rear blade heights are calculated to tailor that co-witness to the shooter s preference whether that means a lower third co-witness or a more centered overlay. Serrations on both sights cut glare in bright conditions keeping the sight picture clean and fast to acquire. Built for the Glock 17 19 45 and 47 MOS slides this sight set is machined and finished with a durable nitride coating that resists wear and corrosion through heavy use. Unlike many fiber optic sight sets designed around a suppressor height Night Fision built this set specifically to work with optics rather than tall sight pictures meant to clear a can. That distinction matters for shooters who want their irons to serve as a practical backup under a red dot rather than a suppressor-height compromise. For Glock MOS owners running an RMR 507C SR or ARCO footprint optic the Night Fision Optics Ready Fiber Optic Sight Set is available for sale at GrabAGun.
