The RM have lost their marbles!
A lot of airguns are sent throught the post described as something else like "measuring instruments" because some shippers are touchy and some shippers are thieves!!
All the little gun bits are sent in a jiffy bag with no reference to the contents and probably go unoticed.
You only have to look on Ebay to see the large quantity of shooting products posted every day of the week.
If the RM really are stupid enough to ban this stuff, firstly, how will they know whats in the bag!?
And secondly, a lot of people will be knocking on their door with a justifiable complaint.
