PROBLEM: No licence or registration is required to own a crossbow in the United Kingdom. Under the Crossbows Act 1987, crossbows cannot be bought or sold in England, Wales or Scotland by or to those under 18. Possession is also prohibited by those under 18 years old except under adult supervision. The act states that crossbows may be used by persons under 18 years of age only when supervised by a person aged 21 years old or over.
