Bulgaria
Airsoft is a legal sport in Bulgaria and there are no restrictions placed on the guns apart from a parents' permission for people under 18. As airsoft guns are considered air guns by the Bulgarian law, no documents, licenses or anything else is needed to possess them. There are no restrictions about lasers, flashlights etc. Moreover, there is no need for the end of the barrel to be painted in orange (like in the United States). There are neither restrictions about the power of the air guns/airsoft guns nor about carrying them in public areas.
Shooting in "protected" (quote from the law) areas is forbidden. Protected areas are schools, administrative buildings and other public property as well as public areas.
