Egw Sight Mount For Vortex Viper/Venom Fits Fn/Fns/Fnx Black
$44.99
The EGW Sight Mount for Vortex Viper/Venom is a dovetail-mounted adapter that lets you install a compact red dot sight on your FN/FNS/FNX platform handgun. This mount replaces your rear sight and accepts Vortex Viper and Venom optics—giving you a fast, co-witnessed aiming solution without permanent modifications to your slide. It's built on a progressive-taper dovetail design that slides in smoothly from left to right (muzzle forward), making installation straightforward even for first-timers. Because it's reversible, you can swap it out and restore your original rear sight whenever you want.
The mount ships with all necessary hardware: two button-head cap screws sized for Vortex Viper and Venom optics, plus a 5/64" allen wrench for installation. Blue Loctite (applied per instructions) locks everything down securely. The whole setup is engineered to work with FN/FNS/FNX frames—just not the FNP or 5.7 variants. If you're planning to run a red dot on a duty, carry, or sport-shooting FN handgun, this is a purpose-built, reversible solution that doesn't require permanent modifications.
Installation is straightforward: remove the rear sight, slide the mount into the dovetail, install your Vortex optic with the supplied screws torqued to 15 in/lbs, and you're ready to go. That said, any firearm modification can affect the manufacturer's warranty, and we recommend having a qualified gunsmith handle installation if you're not comfortable with it yourself.
