ATF Forms 1, 3 and 4 explained

What Forms do I Need to File to Get My NFA Item?

If you are buying an NFA item, you must file an ATF eForm 4. If you are building your own suppressor or building an SBR, you must file an ATF eForm 1. Details about the electronic submission of the different ATF forms are covered below.

What is The Difference Between ATF Form 1 and 4?

You may be wondering: what is a Form 1? If you’re building your own NFA item (such as a silencer or short barrel rifle from a braced pistol), submit an ATF eForm 1. The difference between an ATF Form 1 and ATF Form 4 is building the item on your own or purchasing an item that’s been manufactured for that intended purpose. For example, a Form 4 is used when a consumer purchases an item (such as a suppressor), online, or through a dealer. If the suppressor was manufactured and shipped ready to use, you would use a Form 4. If you’re building the suppressor yourself using pieces and parts, you would file a Form 1.

What is a Form 3?

When a customer purchases a suppressor or other NFA item, it will be transferred to the customer’s local dealer using the ATF Form 3. Form 3s initiate a transfer from one federal firearms licensee (FFL) to another FFL, usually for the purpose of facilitating a sale to a customer in another state. Form 3s do not involve the making of a new suppressor or other NFA item.

What Is A Form 4?

Unless you are a federal firearms licensee (FFL), you will need to file a Form 4 in order to purchase an NFA item such as a suppressor, short barrel rifle (SBR), short barrel shotgun (SBS), machine gun, or any other weapon (AOW). Example: If you live in any of the 42 states where suppressors are legal and purchase a suppressor, the seller will prepare a Form 4, which you will need to certify, in order for the ATF to approve and register the transfer of the suppressor to you. Prior to December 2021, this likely would have been a paper form, but can now be processed electronically as an ATF eForm 4.
