Romania
Law nr. 295 from 2004 (Regimul Armelor şi Muniţiilor) regulates all use of firearms and associated ammunition. The law is quite unclear (in what concerns airsoft firearms) as to whether this kind of firearm classifies as "non-lethal weapon" or "toy." The law regulates the use of air-powered firearms (e.g. sport/competition use that use a metal projectile) under "non-lethal" category and solely requires that you are at least 18 years old and register your firearm at the police precinct nearest to your location.
The law specifies that usage of night vision (infrared) or laser aiming devices designed for military use is completely restricted to members of the army and associated entities even if the aiming device is used on a lower-restriction category firearm (e.g. such as on an airsoft gun). The law, however, does not restrict in any way the use of aiming devices not designed for military use.
Furthermore, the law specifies that, should you attempt to use a non-lethal or replica gun to perform (or attempt to perform) armed robbery, you shall be prosecuted as if a real gun had been used.
A new addition to the law 295/2004 was made at 17 February 2008 called OUG 28/2008 which add further restrictions to the forms and regulations.
Since 23 February 2010, in Romania, based on an airsoft competition and its regulation, airsoft is officially a sport, not only a welfare activity.
Since June 2011, Airsoft replicas have been inserted in firearms and associated ammunition law as non-lethal weapons which does not require any authorization to buy/sell/own, used for recreational purposes - "E" class in weapons classification. The use of metal projectiles is prohibited by law.
