I am wondering if as an FAC holder, with an open slot for a particular weapon of that calibre and type, if I could buy that weapon legally abroad and bring it to the UK to be registered through the Police licensing authority? I would also as a matter of course inform the Police when I acquired the weapon abroad as it states on my current and renewed FAC. I would declare it at the border when importing it and pay the necessary tax too if required. I would also inform it all to the airline transporting me and the weapon and provide a hard locked case for it. It appears that it ought to be okay to do this. Any advice or idea if this is legal?
