It will. Don't know how anyone else does it but it will likely be similar. Mount scope leaving screws loose enough that scope can be rotated. Shoulder xbow many times and set your eye relief. Set focus for your eye. While doing this get the vertical hair close as you can. Level the xbow on a table or something that is stable. I use wood blocks and shims under the limbs. Hang a weighted string in front of your target(masons line with a plumb bob or a heavy bolt). Get the vertical hair on that string and rotate until the vertical plane matches. Check that xbow is still level. If not make adjustments and go back to scope and finish the vertical. Carefully tighten down scope mounts the way described by Excalibur. Check vertical one more time. This gives a very precision mounting and eliminates some variables in your search for accuracy.
