ATF Ruling:Rifles Configured From Pistols, and Offers Q&A’s Related to Multiple Long Gun Reporting

Pistols Configured from Rifles; Rifles Configured from Pistols ATF has issued a new Ruling regarding Pistols Configured from Rifles; Rifles Configured from Pistols
ATF Rule 2011-4

The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) has received requests from individuals to classify pistols that are reconfigured into rifles, for personal use, through the addition of barrels, stocks, and other parts and then returned to a pistol configuration by removal of those components. Specifically, ATF has been asked to determine whether such a pistol, once returned to a pistol configuration from a rifle, becomes a “weapon made from a rifle” as defined under the National Firearms Act (NFA).

After a bunch of analysis, the ATF found the following
Held, a firearm, as defined by the National Firearms Act (NFA), 26 U.S.C. 5845(a)(3), is made when un-assembled parts are placed in close proximity in such a way that they:

(a) Serve no useful purpose other than to make a rifle having a barrel or barrels of less than 16 inches in length (e.g., a receiver, an attachable shoulder stock, and barrel of less than 16 inches in length); or (b) Convert a complete weapon into such an NFA firearm, including –

  1. A pistol and attachable shoulder stock; and
  2. A rifle with a barrel of 16 inches or more in length, and an attachable barrel of less than 16 inches in length.


Such weapons must be registered and are subject to all requirements of the NFA.

Held further, a firearm, as defined by 26 U.S.C. 5845(a)(3) and (a)(4), is not made when parts in a kit that were originally designed to be configured as both a pistol and a rifle are assembled or re-assembled in a configuration not regulated under the NFA (e.g., as a pistol, or a rifle with a barrel of 16 inches or more in length).

Held further, a firearm, as defined by 26 U.S.C. 5845(a)(3) and (a)(4), is not made when a pistol is attached to a part or parts designed to convert the pistol into a rifle with a barrel of 16 inches or more in length, and the parts are later un-assembled in a configuration not regulated under the NFA (e.g., as a pistol).

Held further, a firearm, as defined by 26 U.S.C. 5845(a)(4), is made when a handgun or other weapon with an overall length of less than 26 inches, or a barrel or barrels of less than 16 inches in length, is assembled or produced from a weapon originally assembled or produced only as a rifle. Such weapons must be registered and are subject to all requirements of the NFA.

If you have an item that you previously thought was ok, but is now regulated by the NFA you should obtain a Form 1 approval and tax stamp to make a NFA firearm. Possession of a firearm that you previously though was not a NFA firearm, is not a defense to continued possession of a NFA firearm.
