Allowing us to use magnifying optics such as the 4x Acog and the 6x Acog on the crossbow only makes sense if we can zero these optics to the inherent 25m zero of the crossbow.
Suggestion: These optics can keep their default Zero (4x ACOG = 100m, not sure what the 6x default zero is) but allow us to lower it to 25m with pg down, perhaps only if attached to the crossbow (to avoid confusion for newer players)
