The terms “includes” and “including” do not exclude other things not enumerated which are in the same general class or are otherwise within the scope thereof.
Antique firearm. Any firearm not designed or redesigned for using rim fire or conventional center fire ignition with fixed ammunition and manufactured in or before 1898 (including any matchlock, flintlock, percussion cap, or similar type of ignition system or replica thereof, whether actually manufactured before or after the year 1898) and also any firearm using fixed ammunition manufactured in or before 1898, for which ammunition is no longer manufactured in the United States and is not readily available in the ordinary channels of commercial trade.

The term shall not include an antique firearm or any device (other than a machine gun or destructive device) which, although designed as a weapon, the Director finds by reason of the date of its manufacture, value, design, and other characteristics is primarily a collector's item and is not likely to be used as a weapon. For purposes of this definition, the length of the barrel having an integral chamber(s) on a shotgun or rifle shall be determined by measuring the distance between the muzzle and the face of the bolt, breech, or breech block when closed and when the shotgun or rifle is cocked. The overall length of a weapon made from a shotgun or rifle is the distance between the extreme ends of the weapon measured along a line parallel to the center line of the bore.
Fixed ammunition. That self-contained unit consisting of the case, primer, propellant charge, and projectile or projectiles.
Frame or receiver. The term “frame or receiver” shall have the same meaning as in § 478.12 of this subchapter.
Importation. The bringing of a firearm within the limits of the United States or any territory under its control or jurisdiction, from a place outside thereof (whether such place be a foreign country or territory subject to the jurisdiction of the United States), with intent to unlade. Except that, bringing a firearm from a foreign country or a territory subject to the jurisdiction of the United States into a foreign trade zone for storage pending shipment to a foreign country or subsequent importation into this country, under Title 26 of the United States Code, and this part, shall not be deemed importation.
Machine gun. Any weapon which shoots, is designed to shoot, or can be readily restored to shoot, automatically more than one shot, without manual reloading, by a single function of the trigger. The term shall also include the frame or receiver of any such weapon, any part designed and intended solely and exclusively, or combination of parts designed and intended, for use in converting a weapon into a machine gun, and any combination of parts from which a machine gun can be assembled if such parts are in the possession or under the control of a person. For purposes of this definition, the term “automatically” as it modifies “shoots, is designed to shoot, or can be readily restored to shoot,” means functioning as the result of a self-acting or self-regulating mechanism that allows the firing of multiple rounds through a single function of the trigger; and “single function of the trigger” means a single pull of the trigger and analogous motions. The term “machine gun” includes a bump-stock-type device, i.e., a device that allows a semi-automatic firearm to shoot more than one shot with a single pull of the trigger by harnessing the recoil energy of the semi-automatic firearm to which it is affixed so that the trigger resets and continues firing without additional physical manipulation of the trigger by the shooter.
Make. This term and the various derivatives thereof shall include manufacturing (other than by one qualified to engage in such business under this part), putting together, altering, any combination of these, or otherwise producing a firearm.
Manual reloading. The inserting of a cartridge or shell into the chamber of a firearm either with the hands or by means of a mechanical device controlled and energized by the hands.
Muffler or silencer. Any device for silencing, muffling, or diminishing the report of a portable firearm, including any combination of parts, designed or redesigned, and intended for the use in assembling or fabricating a firearm silencer or firearm muffler, and any part intended only for use in such assembly or fabrication.

Pistol. A weapon originally designed, made, and intended to fire a projectile (bullet) from one or more barrels when held in one hand, and having (a) a chamber(s) as an integral part(s) of, or permanently aligned with, the bore(s); and (b) a short stock designed to be gripped by one hand and at an angle to and extending below the line of the bore(s).
Readily. A process, action, or physical state that is fairly or reasonably efficient, quick, and easy, but not necessarily the most efficient, speediest, or easiest process, action, or physical state. With respect to the classification of firearms, factors relevant in making this determination include the following:
(1) Time, i.e., how long it takes to finish the process;
(2) Ease, i.e., how difficult it is to do so;
(3) Expertise, i.e., what knowledge and skills are required;
(4) Equipment, i.e., what tools are required;
(5) Parts availability, i.e., whether additional parts are required, and how easily they can be obtained;
(6) Expense, i.e., how much it costs;
(7) Scope, i.e., the extent to which the subject of the process must be changed to finish it; and
(8) Feasibility, i.e., whether the process would damage or destroy the subject of the process, or cause it to malfunction.
Responsible person. In the case of an unlicensed entity, including any trust, partnership, association, company (including any Limited Liability Company (LLC)), or corporation, any individual who possesses, directly or indirectly, the power or authority to direct the management and policies of the trust or entity to receive, possess, ship, transport, deliver, transfer, or otherwise dispose of a firearm for, or on behalf of, the trust or legal entity. In the case of a trust, those persons with the power or authority to direct the management and policies of the trust include any person who has the capability to exercise such power and possesses, directly or indirectly, the power or authority under any trust instrument, or under State law, to receive, possess, ship, transport, deliver, transfer, or otherwise dispose of a firearm for, or on behalf of, the trust. Examples of who may be considered a responsible person include settlors/grantors, trustees, partners, members, officers, directors, board members, or owners. An example of who may be excluded from this definition of responsible person is the beneficiary of a trust, if the beneficiary does not have the capability to exercise the powers or authorities enumerated in this section.
Revolver. A projectile weapon, of the pistol type, having a breechloading chambered cylinder so arranged that the cocking of the hammer or movement of the trigger rotates it and brings the next cartridge in line with the barrel for firing.
Rifle. A weapon designed or redesigned, made or remade, and intended to be fired from the shoulder and designed or redesigned and made or remade to use the energy of the explosive in a fixed cartridge to fire only a single projectile through a rifled bore for each single pull of the trigger, and shall include any such weapon which may be readily restored to fire a fixed cartridge.
(1) For purposes of this definition, the term “designed or redesigned, made or remade, and intended to be fired from the shoulder” shall include a weapon that is equipped with an accessory, component, or other rearward attachment (e.g., a “stabilizing brace”) that provides surface area that allows the weapon to be fired from the shoulder, provided other factors, as described in paragraph (2), indicate that the weapon is designed, made, and intended to be fired from the shoulder.
(2) When a weapon provides surface area that allows the weapon to be fired from the shoulder, the following factors shall also be considered in determining whether the weapon is designed, made, and intended to be fired from the shoulder:
(i) Whether the weapon has a weight or length consistent with the weight or length of similarly designed rifles;
(ii) Whether the weapon has a length of pull, measured from the center of the trigger to the center of the shoulder stock or other rearward accessory, component or attachment (including an adjustable or telescoping attachment with the ability to lock into various positions along a buffer tube, receiver extension, or other attachment method), that is consistent with similarly designed rifles;
(iii) Whether the weapon is equipped with sights or a scope with eye relief that require the weapon to be fired from the shoulder in order to be used as designed;
(iv) Whether the surface area that allows the weapon to be fired from the shoulder is created by a buffer tube, receiver extension, or any other accessory, component, or other rearward attachment that is necessary for the cycle of operations;
(v) The manufacturer's direct and indirect marketing and promotional materials indicating the intended use of the weapon; and
(vi) Information demonstrating the likely use of the weapon in the general community.
Shotgun. A weapon designed or redesigned, made or remade, and intended to be fired from the shoulder and designed or redesigned and made or remade to use the energy of the explosive in a fixed shotgun shell to fire through a smooth bore either a number of projectiles (ball shot) or a single projectile for each pull of the trigger, and shall include any such weapon which may be readily restored to fire a fixed shotgun shell.
Transfer. This term and the various derivatives thereof shall include selling, assigning, pledging, leasing, loaning, giving away, or otherwise disposing of. For purposes of this part, the term shall not include the temporary conveyance of a lawfully possessed firearm to a manufacturer or dealer qualified under this part for the sole purpose of repair, identification, evaluation, research, testing, or calibration and return to the same lawful possessor.
