Most of your quality X bows will have either iron adjustable sights, or a low fix powered scope. I really don't think someone is going to try and use one of these without some type a sighting device.I voted no also
Comparing them to a rifle is a stretch, they are only accurate out to 40 maybe 50 yards then the heavy bolt drops off fast.
Also most of them I have seen don't have open sights, just a scope mount, We don't want people hunting with no sights, do we?
