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.

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.

Installation Instructions
- Remove the rear sight*
- Install the EGW Sight Mount in the dovetail
- 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 5/64'' allen wrench for installation.
