Hold up, people. The man is struggling with a foreign language trying to understand us. It is no use using txt spk, contractions, or incomplete sentences, nor assuming he must know things which we take for granted.
1) You do not have to paint your G36 to import it into this country, because you are an airsofter already. The problem is proving it. At the moment, the only quick way, which UK Customs & Excise will recognise, is a UKARA registration number written on the package, with your phone number (just in case) as part of your address is best, like this:
UKARA# XYZ01234
Mr. A. R. Softer
368 Hit Street
Luton
LU8 2XX
UK
Phone: 447789 555123
2) You do not need personal insurance. You will be covered by the insurance of the airsoft site where you play. The part you quoted refers to site owners or event organisers. (The way the law works and how it applies to players and UKARA is quite difficult to explain simply. Trust me, there are many people who believe they understand English perfectly well who nevertheless do not actually understand UK law as it applies to airsoft. This is not really their fault however, because the law is actually so stupid that people probably cannot quite bring themselves to believe that it really means what it says )
3) To get UKARA registered, all you need to do is go airsofting 3 times in not less than 2 months, but you must tell the organisers that you want to get a UKARA number.
It will be best if you tell them every time you go. You will have to provide some identification: something that says who you are, like your passport, and something which says where you now live, such as a letter from your electricity supplier. You will have to fill in a form with your details, which the site organisers will stamp to show that you have attended. After your third game, they will send the form to UKARA. Hopefully it will not be longer than 1 week later before you have your UKARA number, however sometimes it can take longer.
Some sites do not bother to stamp the form. They just keep a record of who is there and fill in the form later. You will have to ask how your local site do it. Understand this however, many sites will tell you that you MUST become a member of their site to become a UKARA registered player. This is not true. It may be more trouble for you to argue than it is worth though. If the membership costs £25-35 for a year and gives you cheaper entry (£5 discount for members is usual), then it is probably best to just pay it. If becoming a member is more expensive and/or does not give any benefits to members, come back and I, or someone else, will explain how to get UKARA registered without becoming a site member.
4) You do not need to be UKARA registered to play.
5) You do not need to paint your gun. The law says that it is illegal to sell you an airsoft gun which looks real (Realistic Imitation Firearm / RIF) unless you are an airsofter. It is also illegal to make an RIF unless you are an airsofter, which means you cannot repaint a brightly coloured airsoft gun, unless you are an airsofter plus it is illegal to import an RIF unless it is for airsofting. However it is not illegal to own an RIF.
Can anyone remember what that Polish lad who used to post on here was called? Alex, you know who I mean, right? I just remember nicknaming him 'Alphabet' because his real name is Alabrudzinski or something similar, but I think his username was from gaming...
