Provides that where a Northern Ireland resident purchases or acquires a firearm, falling within Category C (firearms subject to declaration) for the purposes of Annex 1 of the European weapons directive, in another member State, he must within 7 days advise the Chief Constable. He is not required to do so where the firearm is to be used in and is not to be removed from that member State. Neither is he required to do so where he holds a firearm certificate for the firearm and it contains a condition that he has it as part of a collection. Failure to comply is an offence.
