I think they check the name with the registered UKARA member though and don't clear it if it doesn't match. However you're addressing it to your dad right? They should clear it if they don't get butthurt over it.
Yeah it'll be all in his name. Just seen it says when you are in the cart that UK customers should write their UKARA number in the 'order commentary' so I'll write it in both the address and comments / notes thing to make sure.
Yeah that's what I do. Sometimes customs just get butthurt and keep it anyway. Bought an airsoft M14 a few months ago. Had UKARA number and everything on it and they didn't clear it.
