Article 67 - Conversion of weapons
Makes it an offence for a person other than a firearms dealer to shorten the barrel of a shotgun to a length less than 60.96 centimetres or to convert into a firearm anything which, though having the appearance of a firearm, is incapable of discharging a missile. A person who possesses, purchases or acquires a shortened shotgun or a converted firearm without a firearm certificate shall be treated for the purposes of punishment as having committed the offence in an aggravated form.
