Hi all up till now i have only every purchased rifles and moderators, but I have just sold my HMR. I have downloaded the forms from kent police. I have completed 1 form for the moderator and one for the rifle to say that I have sold them. I also gave the buyer 2 and he filled them in at the same time to say he has purchased from me. I have also complete table 1 on his FAC for the rifle and moderator. I know we both have to post (recorded) to the firearms department. Now what do I do with my cert, I believe that i do not need to send it in but if I want the slot for HMR or a 1 for 1 with a caliber change do I have to do it straight away or can I do it in a few months ?
