You have to read it all very carefully, it may be deliberately worded to confuse, but initially
( this is the Post Office )it says in PROHIBITED GOODS ( weapons) "Including Section 5 firearms (e.g. handguns, machine guns), CS gas and pepper sprays, flick knives, tasers and stun guns. Items that appear to be prohibited weapons may be subject to additional checks and delays " SO THAT LOT MENTIONED YOU CANNOT SEND.
It then goes on to say YOU CAN STILL SEND " Guns for sporting use, including Section 1 (e.g. hunting rifles), Section 2 (e.g. shotguns) firearms and low-powered air weapons may be sent in compliance with UK law and subject to domestic controls on the possession of firearms. Please see Restricted Goods page." SO THAT LOT JUST MENTIONED YOU CAN STILL SEND.
It then adds the following from the restricted goods page " Guns intended for sporting purposes - including Section 1 (e.g. hunting rifles) and Section 2 (e.g. shotguns) firearms, low-powered air weapons and their component parts - may be sent in compliance with UK law and subject to domestic controls on the possession of firearms. Antiques, deactivated and imitation firearms are also permitted. When sending deactivated firearms include proof of deactivation. Items that appear to be prohibited weapons may be subject to additional checks and delays. Please see the Prohibited Goods page. Use 1st Class as the minimum service. The sender?s name and address must be clearly visible on the outer packaging" SO AGAIN STATING CLEARLY that sect 1 & 2 ( rifles & shotguns ) can still be sent together with `low powered air guns( sub 12ft/lb & 6 ft/lb presumably otherwise they come under Sect 1 !! ??.)
THE UPSHOT OF ALL THE ABOVE IS THAT THE Post Office SHOULD accept Airguns for posting as they do not come under wepaons that are prohibited... .
