I have always informed the Police by recorded delivery within 7 days of a new purchase of a rifle or shotgun. Most RFD's will give you a pre- completed form you simply sign and send off.
I now purchased a new rifle (the slot on my FAC was previously granted) and my RFD insists I do NOT have to inform my Force, it is only the SELLER who has that duty.
So who is right, who is wrong?
I will cover my back by informing my Force anyway, but I am interested to find out if I really should.
