How to Replace a Windage Knob

A typical rifle scope uses two different adjustments, typically controlled by small knobs. These are the windage and elevation knobs. The windage knob is used to adjust the scope in the horizontal axis, while the elevation knob adjusts the vertical axis. Because the knobs are moving parts, they are susceptible to wear and tear and may break off, requiring replacement. Replacing the knob is a straightforward process, requiring one quick calibration.

Instructions

    • 1

      Make sure the rifle is unloaded and the safety is on. Keep the firearm pointed in a safe direction away from people.

      Remove any remaining parts of the broken knob on the side-mounted windage dial. Look for the windage dial on the side in the middle of the rifle scope. Dip a small rag into some grease remover and wipe down the windage screw. Clean out any grit or grime from the screw.

      Screw the new windage knob onto the screw. As you screw this down, you end up moving the calibration of the crosshairs on the scope. Screw the knob until it cannot move further. If you wish, add a quick dollop of grease to the screw prior to turning the knob onto it.

      Take the rifle to a safe shooting area and take practice shots to readjust the rifle scope with the new knob.
