caliber air guns require a FAC or a hunting license. An expired hunting license is valid for bigger caliber air guns, as long as the license holder legally would be able to renew it. An air gun with a caliber over 4.5 mm (0.177) must be kept in a locked, approved gun cabinet. Air guns with the caliber of minimum 5.5 mm (0.22) are legal for hunt. Finland The acquisition and ownership of air guns is unrestricted unless they meet the definition of an effective air gun as defined in the 2015 amendment to the Firearms Act of 1998. Any air gun that has a barrel diameter exceeding 6.35 millimeters or .25 inches, shoots metal projectiles, and was not manufactured before 1950 is considered an effective air gun. Some provisions of the Firearms Act apply to effective air guns in addition to firearms, including the requirement to obtain a separate licence for each such gun. The possession of air guns in a public place without a valid reason is prohibited under the Public Order Act, as is shooting in a manner that disturbs public order or endangers public security. Additionally, to permanently hand over air guns to a person under the age of 18 without the permission of their guardian is prohibited. Under the Hunting Decree of 1993 as amended in 2019, air guns may not be used to shoot animals except inside a building to kill crows, common magpies, jackdaws, rock pigeons, and unprotected mammals other than feral cats. France Since September 2013, air rifles with a muzzle energy less than 20 joules (14 ft lbf) can be acquired by persons over age 18 and no licence is required. (Previously the limit was 10 joules.) For air rifles of 20 joules muzzle energy or more, a hunting licence or club shooting licence is required. However, hunting or pest control with air guns is illegal in France. Germany In Germany, air guns producing a muzzle energy up to 7.5 joule (J) (5.53 ft·lbf) can be owned by persons from the age of 18 years and freely acquired provided they bear the "F-in-pentagon" mark that indicates a muzzle energy not exceeding kinetic energy. Carrying air guns in public necessitates a carry permit (§ 10 Abs. 4 WaffG), extremely rare as such and never granted for air guns. Only the transportation of unloaded and non-accessible air guns (or carrying unloaded during biathlon)
