Delaware prohibits any person from selling, transferring, purchasing, receiving or possessing a “destructive weapon,” including any machine gun or firearm that is adaptable for use as a machine gun.1 This prohibition does not apply to: 1) members of the U.S. military or a police force in Delaware duly authorized to carry a machine gun; or 2) persons possessing machine guns for scientific or experimental research and development purposes, which firearms have been duly registered under the National Firearms Act of 1968 (26 U.S.C. § 5801 et seq.).2

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, 1986.3 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, 2019.4

In 2018, Delaware prohibited any person from selling, transferring, purchasing, receiving or possessing bump stocks and trigger cranks, which are firearm accessories that can significantly increase its rate of fire to function similarly to a machine gun. In October, 2017, a shooter used multiple bump stock devices in an attack on concert-goers in Las Vegas to perpetrate the deadliest mass shooting attack in modern history.

Delaware defines a “bump stock” as “an after-market device that increases the rate of fire achievable with a semi-automatic rifle by using energy from the recoil of the weapon to generate a reciprocating action that facilitates repeated activation of the trigger.”5 It defines a “trigger crank” as “an after-market device designed and intended to be added to a semi-automatic rifle as a crank operated trigger actuator capable of triggering multiple shots with a single rotation of the crank.”6
