    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.

    - 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.)

    - Torque mounting screws to 15in/lbs
