I can sort of understand why RM and PF have some concerns / issues carrying a PCP or bottle due to the pressurised cylinder. If one was sent that was faulty, cracked etc. and the way that some of the parcels are treated in transit, it's a potential accident waiting to happen.
But when I comes to spring powered rifles and pistols, I can't see an issue. As long as what is inside the parcel is not written brazenly on the outside and packages sufficiently, how would anyone know what was in there during transit? The only people likely to know are the person sending it, the receipient and (possibly if told) the person taking the parcel from the sender at the post office. And what damage could they possibly cause?
I understand the insurance side of things, but this is the post office not wanting to pay out loads more on th parcels they loose / damage. And I have had a few of these instances in the past.
