(a) All essential parts of a deactivated firearm are to be rendered permanently inoperable and incapable of removal, replacement or modification in a manner that would permit the firearm to be reactivated in any way;
(b) Arrangements are to be made for deactivation measures to be verified, where appropriate, by a competent authority to ensure that the modifications made to a firearm render it permanently inoperable;
(c) Verification by a competent authority is to include a certificate or record attesting to the deactivation of the firearm or a clearly visible mark to that effect stamped on the firearm.
