With the increased security on international (and internal) flights in the last few decades, what is the best way to transport airsoft rifles and pistols between countries?
There are several large international airsoft skirmishes - the most notable one that comes to mind is Berget in Sweden (http://www.berget-events.com/).
In the majority of cases, does an additional licence or permit need to be purchased? If there are specific, relevant exceptions please indicate these.
If a flight connects through a country where airsoft guns are illegal/banned, are there any further actions to be taken with the intermediate country?
Is there a service available (such as a courier service) that could be used to transport the weapons, so they don't need to be transported as luggage?
An answer to this might also apply to other shooting/archery sports, especially if countries worldwide do not make a distinction between airsoft weapons (which are basically non-lethal) and other projectile weapons.
