Just submitted this email query to HMRC, we'll see if they respond!
"I'm a member of the UK military and I'm currently living and working in the USA on an authorised deployment. During my deployment I have taken up the hobby of 'airsoft'.
My query relates to bringing (importing) my Realistic Immitation Firearms (RIFs) that I use for this hobby back into the UK at the end of my deployment. I am likely to return to the UK via Heathrow airport.
I've read around the UK law and understand the defences against the Violent Crime Reduction Act (VCRA), specifically section 36(1)(d), and the offence of importing a RIF into the UK.
Given, this my defence would be under:
"the organisation and holding of permitted activities for which public
liability insurance is held in relation to liabilities to third parties arising
from or in connection with the organisation and holding of those
activities".
I am aware of the UKARA scheme, that allows airsoft retailers to sell airsoft RIFs to UKARA members in the UK, but to my understanding this is not necessarily a VCRA defence. Rather, membership of UKARA provides evidence of participation in the hobby, which can be used to support the defence stated above.
I will be unable to complete my UKARA membership prior to returning to the UK (play 3 airsoft games over a period greater than 2 months at a registered site).
Given this, I'm unsure how I prove that I'm a 'skirmisher' participating in this hobby, as so far I have only participated in airsoft events in the USA."
I didn't realise the law would be so unclear!
