Product Info for Evolution Gun Works Vortex Viper/Venom Sight Mount Oversized

This mount is NOT a drop in part and will require fitting. Our red dot sights are meant to be installed from the left to the right (with the muzzle facing forward). The dovetail has a progressive taper to allow for easier install.image

Simply remove the rear sight on your gun and replace it with our mount in order to mount your Vortex Viper/Venom, Burris FastFire, or Docter red-dot sight. You can take our mount off and replace your rear sight at any time. Mounting hardware included. Our products should be installed and checked by a qualified and competent gunsmith.

Installation Instructions: Remove the rear sight. Install the EGW Sight Mount in the dovetail after checking for fit. Tighten set screw (if applicable). Place the red dot sight on the EGW Sight Mount (placing a small piece of paper between the red dot sight and the sight mount will make for easier removal and will keep Loctite off of the red dot sight.) Apply blue Loctite to the provided mounting screws. Torque mounting screws to 15in/lbs.

2 Button Head Cap Screws - Provided for Vortex Viper and Venom Sights. 2 Flat Head Cap Screws - Provided for Burris FastFire and Docter Sights. The screws that are included with this mount require a 5/64in allen wrench for installation. Modification of your firearm may nullify the manufacturer's warranty. This product should be installed and checked by a qualified gunsmith. No liability is expressed or implied for damage or injury which may result from improper installation or use of this product.

All ADE mounts require 6-32 x 3/8in screws.

This mount fits: Firearms with oversized Novak cut dovetails. This mount is made .007in larger than a standard Novak cut and will require fitting.

Please note: We have found that some red dots commonly found on Amazon such as the UTG and ADE may not hold the same tolerances as the red dots that this mount was initially created to work with. These dots may not fit properly on the posts on the plate. We would recommend either sending the red dot back for an exchange to whichever seller you purchased it from, or open up the holes in the bottom of the red dot to accommodate the pins.
