Installation Guide for EGW Red Dot Sight Mount:

Step 1: Remove the rear sight from your gun.

Step 2: Install the EGW Sight Mount in the dovetail. The dovetail has a progressive taper to allow for easier install.

Step 3: If applicable, tighten the set screw.

Step 4: 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).

Step 5: Apply blue Loctite to the provided mounting screws.

Step 6: Torque mounting screws to 15in/lbs. The screws that are included with this mount require a 5/64'' allen wrench for installation.
