what is the minimum legal length for a shotgun
Sawed-off shotgun Under the National Firearms Act (NFA), it is illegal for a private citizen to possess a sawed-off modern smokeless powder shotgun (a shotgun with a barrel length shorter than 18 inches (46 cm) or an overall length shorter than 26 inches (66 cm)) (under U.S.C. Title II), without a tax-paid registration from the Bureau of Alcohol, Tobacco, Firearms and Explosives, requiring a background check and either a $200 or $5 tax for every transfer, depending upon the specific manufacturing circumstances of the particular sawed-off modern shotgun being transferred. Gun trusts have become an increasingly popular means of registering SBS' with the BATFE.[9] Short-barreled muzzleloading blackpowder shotguns, in contrast, are not illegal by federal law and require no tax-stamped permit, although they may be illegal under state law. As with all NFA regulated firearms, a new tax stamp must be purchased before every transfer. Inter-state transfers must be facilitated through a Federal Firearms Licensee (FFL) while intrastate transfers may be between two persons.[10]
Second Amendment to the United States Constitution The Second Amendment (Amendment II) to the United States Constitution protects the right of the people to keep and bear arms and was adopted on December 15, 1791, as part of the first ten amendments contained in the Bill of Rights.[1][2][3][4] The Supreme Court of the United States has ruled that the right belongs to individuals for self defence, but “Like most rights, the right secured by the Second Amendment is not unlimited…”. It is “…not a right to keep and carry any weapon whatsoever in any manner whatsoever and for whatever purpose.” “Nothing in our opinion should be taken to cast doubt on longstanding prohibitions on the possession of firearms by felons and the mentally ill, or laws forbidding the carrying of firearms in sensitive places such as schools and government buildings, or laws imposing conditions and qualifications on the commercial sale of arms.”[5][6] while also ruling that the right is not unlimited and does not prohibit all regulation of either firearms or similar devices.[7] State and local governments are limited to the same extent as the federal government from infringing this right, per the incorporation of the Bill of Rights.[8]
