In the olden days, when you could still purchase a firearm by post, scammers advertised cheap handguns in gun magazines, and when you sent them your FAC in the post together with a cheque, the scammers would discard the cheque then use your FAC to purchase guns by post from a genuine seller... and in those days it was pistols and revolvers that were coveted by the thieves. It amazed me at the time that RFDs did not insist on shipping the firearm only to the registered address on the FAC, which might have stopped this scam. Anyways, you can no longer buy a firearm by post, and in fact you can no longer buy a revolver or a pistol (unless black powder or LBP, obviously). Sad times....
