Laws Regarding Buying and Selling Imitation Firearms Relevant to Airsoft
As the law currently stands (and it stands on the whim of the Home Secretary):
In relation to UNDER 18s:
- it is legal to own an IF or a RIF
- it is illegal to buy an IF or a RIF if you are under 18
- it is illegal to sell an IF or a RIF to an under 18
From 'VCRA 2006' Section 40 -

In relation to OVER 18s:
- it is legal to own an IF or a RIF
- it is legal to buy an IF or a RIF if you are over 18
- it is legal to sell an IF to an over 18
- it is illegal to sell a RIF to an over 18
- it is illegal to manufacture a RIF
- it is illegal to import a RIF
From 'VCRA 2006' Section 36 -
http://www.legislation.gov.uk/ukpga/2006/38/section/36
NOTE 1: if you wish to import a RIF, manufacture a RIF or sell a RIF to an over 18 you can avail yourself of a 'defence against prosecution' if you can show that you believed that you were intending to provide the RIF for "the acting out of military or law enforcement scenarios for the purposes of recreation" (an example of which is 'airsoft skirmishing') at a site with third party liability insurance. One way for a seller to do this is to establish that the buyer is registered with the UKARA database, though this is by no means a legal requirement or the only way for the seller to establish a defence for themselves.

NOTE 2: any attempt to commit one of the offences listed as illegal above is also illegal in itself.
From 'Criminal Attempts Act 1981' Section 1 -
http://www.legislation.gov.uk/ukpga/1981/47/section/1
NOTE 3: the defence required to manufacture a RIF is not age specific, so an under 18 should be able to do so legally as long as they can prove their defence.
