Airsoft guns are subject to gun laws and regulations due to high similarity to real guns (since Waffengesetz of 2008). Therefore they may not be carried nor used in public. Airsoft games must be organised in restricted area and police must be advised. The purchase is free to adults (18yo) (must provide a copy of their ID) except for a few nationalities (citizen of countries ongoing armed conflicts, so they can't buy a gun and send it to their relatives as it is in the US-Mexico).
