Under Section 17 of the Firearms Act 1968, a visitor to Great Britain may, if granted a visitor’s permit, have in their possession firearms, shotguns or ammunition without holding a certificate.
The holder of a visitor’s firearm permit may have in their possession (but cannot purchase) a firearm and they may purchase, acquire or have in their possession any ammunition to which Section 1 of the 1968 Act applies (e.g. rifle ammunition)
The holder of a visitors’ shotgun permit may have in their possession, purchase or acquire shotguns and is exempt from the requirement to produce a shotgun certificate when purchasing cartridges (which must contain 5 or more shot, none of which exceeds .36 inches in diameter).
Visitor’s shotgun permits do not allow the borrowing of shotguns for 72 hours as with UK shotgun certificates.
Visitor’s permits are not only issued to enable firearms to be brought into the UK. They may be issued to allow possession of firearms and shotguns already held in the UK where the visitor needs to possess them without supervision in the same way as if they had brought their own gun from abroad.
