Although it may technically not be considered a firearm, if this is a new item you cannot purchase it online, must be in person. If your transaction goes wrong, PayPal may opt out protecting you.

Air pistols generating more than 6 ft·lbf (8.1 J) and air rifles generating more than 12 ft·lbf (16.2 J) of energy are considered firearms [18] and as such require possession of a Firearms Certificate (FAC). As hand guns are illegal in the UK an air pistol generating more than 6 ft·lbf of energy is a prohibited weapon and cannot be legally owned even on a FAC. Pistols and rifles below these energy levels do not require licensing, and may be purchased by anyone over the age of 18. In Northern Ireland any air rifle or air pistol generating more than 0.737 ft·lbf (1 J) is considered a firearm [19] and as such requires a FAC. The Violent Crime Reduction Act 2006 prohibits online or mail-order sale of new air guns; transactions must be finalised face-to-face, either at the shop where purchased, or through a Registered Firearms Dealer (to which an item may be posted and the transfer completed).
From 10 February 2011, The Crime & Security Act 2010 (S.46) made it an offence "...for a person in possession of an air weapon to fail to take reasonable precautions to prevent any person under the age of eighteen from having the weapon with him...".[20] This legislation essentially relates to the storage of air guns and the requirement of owners to prevent unauthorised access by children. Failure to do so renders owners liable for a fine of up to £1,000.[21]
Any person on private property (land or water) without permission is trespassing; possession of an air gun when doing so, with or without ammunition, loaded or unloaded is armed trespass, and is considered a serious criminal offence subject to heavy penalties.[22]
