Egw Sight Mount For Vortex Viper/Venom Fits Ruger Auto Black
The EGW Sight Mount for Vortex Viper/Venom is a dovetail-mounted adapter designed to accept red dot optics on Ruger Auto pistols with rear dovetail cuts. If you're running a Vortex Viper or Venom red dot and want a clean, repeatable way to install it on your carry gun or range pistol, this mount handles the job without permanent modifications. The progressive-taper dovetail design makes installation straightforward, and the mount can be removed and reinstalled without affecting your factory rear sight — swap it back whenever you need the original sights.
Installation is mechanical and requires attention to detail. The mount slides into your Ruger's factory dovetail (left to right, muzzle forward) and locks down with a set screw. Your Vortex optic then mounts to the top of the EGW platform using the included button-head cap screws, torqued to 15 in/lbs with blue Loctite. The dovetail's progressive taper reduces binding during install and removal, which matters when you're swapping between your factory sights and an optic. Because this involves firearm modification, EGW and responsible manufacturers recommend professional installation by a qualified gunsmith — improper installation can affect reliability and safety.
This mount comes ready to go: the two button-head cap screws fit the Vortex Viper and Venom, and a 5/64" allen wrench is all you need to secure them. If you're considering a Burris FastFire or Docter sight instead, those use the included flat-head screws. Keep in mind that optics-ready modifications can void your firearm's factory warranty, so verify the details with your gun's manufacturer before proceeding.

Frequently Asked Questions
Will this mount work with Burris FastFire or Docter red dots?
Yes. The EGW mount includes both button-head cap screws (for Vortex Viper/Venom) and flat-head cap screws (for Burris FastFire and Docter sights), so it's adaptable to all three platforms. However, this product is marketed for the Vortex Viper/Venom on Ruger Auto, so confirm compatibility with your specific optic before ordering.
Can I remove this mount and go back to my factory rear sight?
Yes. The EGW mount can be uninstalled from the dovetail, and your original rear sight can be reinstalled in its place. This makes it a reversible upgrade if you want to keep your options open.
What's included in the box?
The mount includes all necessary mounting hardware: two button-head cap screws for Vortex Viper/Venom installation, two flat-head cap screws for Burris FastFire or Docter optics, and the information you need to torque them properly. You'll need to supply blue Loctite and a 5/64" allen wrench.
Should I install this myself?
Because this modification involves removing and replacing your firearm's rear sight, EGW recommends professional installation by a qualified gunsmith. Improper installation can affect reliability, accuracy, and safety. Also note that mounting an optic may void your Ruger's manufacturer warranty, so check with Ruger before proceeding.
