XS Sight Systems Standard Dot Features The XS Sight Systems Standard Dot front sight uses a hand polished brass bead with a convex face which reflects more light than flat faced factory or competitor sights for a cleaner more visible sight picture. The bead measures 0.140 inches giving it the kind of classic retro profile that revolver shooters have relied on for high visibility sighting at the range or in the field. Hand polishing with Flitz polishing products brings out the brass finish while a light protective layer helps minimize oxidization over time. Though brass does not replace tritium for low light EDC use it excels for daylight shooting where contrast and visibility matter most. Built from durable CNC machined steel this front sight is designed specifically to fit the Colt Viper giving owners a precise drop in upgrade over the factory sight. The kit includes the front sight itself blue threadlocker a hex wrench for the front sight set screw and an insert with installation instructions. This makes installation straightforward for most owners without needing a gunsmith. For Colt Viper shooters who want a more visible front sight with a classic look and genuine durability the XS Sight Systems Standard Dot brass sight is a worthwhile upgrade.
