Louisiana law prohibits the sale, transport, purchase and possession of a machine gun, with few exceptions.¹ The law also prohibits any merchant or manufacturer from permitting any machine gun to pass from his or her possession to the possession of any person unless the person falls within one of the exceptions.² Every manufacturer or merchant must keep a register of all machine guns manufactured or handled by him, which must include the: 1) date of the sale, loan, gift, delivery, or receipt of any machine gun; 2) name, address, and occupation of the person to whom the machine gun was sold, loaned, given, or delivered, or from whom it was received; and 3) purpose for which the person, to whom the machine gun was sold, loaned, given, or delivered, purchased, or obtained it.³

Federal law requires machine guns to be registered with the Bureau of Alcohol, Tobacco, Firearms & Explosives (ATF), and generally prohibits the transfer or possession of machine guns manufactured after May 19, 1986.⁴ In December 2018, ATF finalized a rule to include bump stocks within the definition of a machine gun subject to this federal law, meaning that bump stocks will be generally banned as of March 26, 2019.⁵
