Title II weapons
These are weapons requiring a Type 01 Federal Firearms License (FFL) as well as a Class 3 Special Occupation Tax (SOT) to sell, and an ATF Form 4 (transfer of registration) with $200 tax stamp to purchase. The restrictions apply to certain firearms, explosive munitions, and other devices which are federally regulated by the (NFA). Any violation of the NFA is a felony punishable by up to 10 years in prison. Per the National Rifle Association's Summary of Gun Control Act of 1968:
Title II of the Gun Control Act of 1968 is a revision of the National Firearms Act of 1934, and pertains to machine guns, short or "sawed-off" shotguns and rifles, and so-called "destructive devices" (including grenades, mortars, rocket launchers, large projectiles, and other heavy ordnance). Acquisition of these weapons is subject to prior approval of the Attorney General, and federal registration is required for possession. Generally, a $200 tax is imposed upon each transfer or making of any Title II weapon.
The Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF), which enforces federal firearms law, refers to such weapons as "NFA firearms". NFA firearms include machine guns, short-barreled rifles and shotguns, heavy weapons, explosive ordnance, silencers and "any other weapon" (AOW), such as disguised or improvised firearms. Title I weapons or GCA firearms are standard rifles, shotguns and handguns.
Explosive devices such as bombs or grenades are regulated as NFA firearms (destructive devices). Explosive materials are not considered NFA firearms; they are regulated under the Organized Crime Control Act.
A machine gun, as defined in the NFA, is "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 NFA term machine gun refers to all firearms capable of full automatic fire and includes true machine guns, assault rifles, battle rifles, submachine guns, and machine pistols. The frame or receiver of a machine gun, and any combination of parts intended to make a machine gun, is legally defined as a machine gun. For example, according to the ATF, "A Glock conversion switch is a part designed and intended for use in converting a semi-automatic Glock pistol into a machine gun; therefore, it is a "machine gun" as defined in 26 U.S.C. 5845(b)."
Parts that can be used to convert a semi-automatic firearm to fully automatic capability are regulated as machineguns and must be registered and tax paid under the NFA. The US Military issued kits T17 and T18 to convert the M1 carbine to an M2, capable of fully automatic fire; these kits are legally "machine guns".
(1) a shotgun having a smoothbore barrel or barrels of less than 18 inches in length;
(2) a weapon made from a shotgun if such weapon as modified has an overall length of less than 26 inches or a barrel or barrels of less than 18 inches in length [...]
(3) a rifle having a rifled barrel or barrels of less than 16 inches in length;
(4) a weapon made from a rifle if such weapon as modified has an overall length of less than 26 inches or a barrel or barrels of less than 16 inches in length [...]
ATF regards pistols with shoulder stocks as redesigned to be fired from the shoulder. Modern pistols with shoulder stocks and with barrels less than 16 inches long, or overall length under 26 inches, are NFA short barrelled rifles. ATF has removed some specified stocked handguns (e.g., original Mauser C96 and Luger utilizing an original shoulder stock) from the NFA as collectors' items (Curios or Relics List); ATF treats them as pistols under the GCA.
- Explosive ordnance
- Any explosive, incendiary, or poison gas, including bombs, grenades, rockets, missiles, mines and similar devices (e.g. grenade launchers, rocket launchers). Parts intended for making such a device are also DDs. Small rockets, with less than 4 ounces (113 grams) of propellant, are exempt.
- Large bore firearms
- Any projectile weapon with a bore diameter greater than 1⁄2 inch (50 caliber, 12.7 mm), except for shotguns "generally recognized as particularly suitable for sporting purposes".
Most commercial shotguns have a bore diameter greater than 1⁄2 inch, but are exempt due to their "sporting purpose"; however, both the Street Sweeper and USAS-12 shotguns, designed for military or police use, were reclassified as DDs when the ATF determined they were combat shotguns not "generally recognized as particularly suitable for sporting purposes".
Devices which are not intended or not likely to be used as a weapon are also exempt. Examples of non-weapon large bore firearms include:
- Line-throwing devices for marine rescue, such as lyle guns and rockets for breeches buoys.
- Civilian flare guns, which fire 37 mm flare caliber (1.46 inch) non-weapon rounds.
Fireworks are non-weapon explosive ordnance.
Flare launchers are normally exempt as they are signalling devices, not weapons; however, possession of a flare launcher and anti-personnel ammunition for it puts it in the DD category as it is then considered to be a weapon.
The legal term silencer, technically known as a "suppressor", is defined as "any device for silencing, muffling, or diminishing the report of a portable firearm, including any combination of parts ... intended for use in assembling or fabricating a firearm silencer."
Any other weapon
"Any other weapon" is a "catch-all" category. An AOW as defined as "any weapon or device capable of being concealed on the person from which a shot can be discharged through the energy of an explosive," other than a handgun with a rifled barrel". This umbrella definition includes many improvised firearms ("zip guns") and disguised firearms. Examples include wallet guns, cane guns, knife guns and pen guns. An AOW can be transferred to non-prohibited persons with a $5 BATF stamp as opposed to the $200 stamp required for machine guns and short-barreled rifles.
AOW is a complex and often misunderstood category of NFA firearms. Less obvious examples of AOW devices include:
- Short-barreled shotguns manufactured without a shoulder stock (less than or equal to 26" overall length)
- They are smooth-bore handguns which fire shot shells, not shotguns, which must be designed to be fired from the shoulder.
- Pistols with a second vertical grip
- Many pistols feature a rail below the barrel, commonly used to mount a laser or flashlight. Attaching a vertical grip to this rail constitutes the manufacturing of an AOW firearm, as it is "no longer designed to be held and fired by the use of a single hand." It is therefore illegal to place an aftermarket vertical foregrip on any pistol without first registering it as an AOW and paying the $200 "making and registering tax". Failure to do so is a felony punishable by up to 10 years in prison. However, if the receiver was originally manufactured to accept either a long or short barrel and a removal buttstock and fore grip and it can be assembled either as a rifle or a pistol, according to ATF rule 2011-4 it is not considered an NFA weapon as long as it is only assembled as a pistol without a buttstock or as a rifle with a barrel at least 16 inches long. A vertical foregrip MAY be added to a pistol as long as the Overall Length (OAL) is greater than 26", regardless of barrel length, and providing the weapon remains unconcealed. An AR-15 pistol with an overall length of 26" or longer may have a vertical foregrip installed, as long as no buttstock is installed in conjunction with a shorter than 16" barrel. The Sig Sauer Pistol Braces (SBS and SBX) are commonly found on these AR-15 style pistols with vertical foregrips since they are not considered buttstocks. The ATF does not consider a weapon in this configuration to be an AOW, but instead classifies it as a 'Firearm' which does not require any tax stamp or additional registration.
- Firearms having combination rifle and shotgun barrels, more than 12 inches but less than 18 inches long from which only a single discharge can be made from either barrel without manual reloading
- these are designed to be fired from the shoulder. An example is the Marble Game Getter an early 20th-century sporting gun sold before the NFA.
- Spud guns
- These may potentially be classified as AOWs because they have a large bore and an unrifled barrel. One of the frequently asked questions on the BATF website FAQs is: "How do I obtain a classification from ATF for my "potato gun?" It is not known at present if the BATF has actually classified any potato gun as an AOW. Such a classification would require the manufacturer to either pay the $200 manufacturing tax, surrender the weapon to the BATF, or destroy it.
The term "antique firearm" means 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.
Muzzle-loading firearms with bores larger than .50 inch are not NFA firearms (destructive device).
The ownership of Title II weapons is not illegal, but is heavily regulated at both the State and Federal level. Numerous federal restrictions are imposed on the ownership of NFA firearms, including an extensive background check, a $200 tax on manufacture or transfer of an NFA firearm, and registration with the NFA registry. Generally, for the manufacture of NFA items, ATF Form 5320-1 must be submitted to the ATF. For the transfer of a NFA item (from a person or entity lawfully entitled to transfer it (Class 3 dealer) to yourself, or an entity (Gun Trust or LLC) then the ATF Form 5320-4 must be submitted to the ATF. There is a lower, $5 transfer tax for weapons that fit in the definition of "Any Other Weapon" (AOW). Any violation of the NFA is a felony punishable by a fine of up to $250,000 and up to 10 years in prison, and any firearm involved is forfeit.
Of NFA firearms (silencers, machine guns, short barrel rifles, short barrel shotguns, any other weapon (AOW) and destructive devices) machineguns are the most restricted. Since 19 May 1986, no new machineguns can be registered for private ownership. The AOW transfer tax is $5 making them the least restricted, but all other NFA rules apply.
State laws on NFA firearms
A few states, such as New York and California, have provisions in their state laws that prohibit ownership of Title II weapons and devices. Most states allow legal ownership if the owner has complied with the federal registration and taxation requirements. A few states only allow possession of NFA firearms on the ATF Curios and Relics List, again only if the owner has complied with all federal requirements.

ATF has long held that by installing a vertical fore grip on a handgun, the handgun is no longer designed to be held and fired by the use of a single hand. Therefore, if individuals install a vertical fore grip on a handgun, they are "making" a firearm requiring registration with ATF’s NFA Branch. Making an unregistered "AOW" is punishable by a fine and 10 years’ imprisonment. Additionally, possession of an unregistered "AOW" is also punishable by fine and 10 years’ imprisonment.
