NFA Items

What's an NFA Item?

Charleston FFL Transfers can assist customers with NFA sales, and transfers. The National Firearms Act (NFA) controls the sale and transfer of Suppressors, Short Barrel Rifles (SBR), Short Barrel Shotguns (SBS), and Machine Guns (Full Auto). We help customers throughout the entire NFA Process and can order most makes and models of suppressors for customers.

The National Firearms Act of 1934 (NFA) defines a number of categories of regulated firearms. These weapons are collectively known as NFA firearms and include the following:


Includes any firearm which can fire repeatedly, without manual reloading, “by a single function of the trigger”,[10] Both continuous fully automatic fire and “burst fire” (e.g., firearms with a 3-round burst feature) are considered machine gun features. The weapon’s receiver is by itself considered to be a regulated firearm. A non-machine gun that may be converted to fire more than one shot per trigger pull by ordinary mechanical skills is determined to be “readily convertible”, and classed as a machine gun, such as a KG-9 pistol (pre-ban ones are “grandfathered”).


Includes any firearm with a buttstock and either a rifled barrel less than 16″ long or an overall length under 26″. The overall length is measured with any folding or collapsing stocks in the extended position. The category also includes firearms which came from the factory with a buttstock that was later removed by a third party.


Similarly to SBRs, but with either a smoothbore barrel less than 18″ long or a minimum overall length under 26″.


The legal term for a suppressor is silencer,[11] and includes any portable device designed to muffle or disguise the report of a portable firearm, but does not include non-portable devices, such as sound traps used by gunsmiths in their shops which are large and usually bolted to the floor.

Destructive devices (DDs)

There are two broad classes of Destructive Devices:
  • Devices such as grenades, bombs, explosive missilespoison gas weapons, etc.
  • Any firearm with a bore over 0.50 inch except for shotguns or shotgun shells which have been found to be generally recognized as particularly suitable for sporting purposes. (Many firearms with bores over 0.50 inch, such as 10-gauge or 12-gauge shotguns, are exempted from the law because they have been determined to have a “legitimate sporting use”.)


The AOW definition includes specifically described weapons with combination shotgun and rifle barrels 12 inches or more but less than 18 inches in length from which only a single discharge can be made from either barrel without manual reloading.
