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]
Gun laws in Washington There are no age restrictions on the possession of firearms and some people are prohibited from possessing firearms due to certain criminal convictions or who are released on bond or their own recognizance pending trial for certain criminal charges. Since July 1, 1994, machine guns, short-barreled shotguns, and any parts thereof are prohibited. Suppressors[4] and short-barreled rifles may be possessed and used in accordance with federal law. Pistols transferred through an F.F.L. dealer must be registered with Washington State D.O.L.[5]
