Do you need FFL for upper receiver?

There are a few things you need to know about FFLs and upper receivers:

1. First, to own an upper receiver, you don’t need to have an FFL. An upper receiver is not a firearm; it’s simply a part of a firearm.

2. Second, even if you don’t have an FFL, you can still legally purchase and possess an upper receiver as long as it’s not attached to a lower receiver.

3. Third, if you want to attach the upper receiver to a lower receiver (which would make it into a functional firearm), you’ll need to have an FFL. The reason for this is that when you attach the two receivers, you’re effectively creating a new firearm. And since firearms must be registered with the government, you’ll need to have an FFL to do so.

So, in short, you don’t need an FFL to own an upper receiver. However, if you want to attach it to a lower receiver and make it into a functional firearm, you will need an FFL.

You don’t need a Federal Firearms License (FFL) to purchase an upper receiver.
An FFL is required to transfer firearms across state lines, but an upper receiver is considered a part, not a firearm. So as long as the seller is located in the same state as the buyer, no FFL is needed.
 

 
That said, there are some important things to keep in mind when purchasing or transferring an upper receiver: first and foremost, make sure that the barrel is permanently attached. Also be aware that if you plan to use your upper receiver with a lower that doesn’t already have a serial number (e.g., if you’re building your AR-15), you’ll need to get the lower receiver engraved with a unique serial number.

An “upper receiver” is simply the upper portion of a rifle barrel that sits on top of the receiver. It doesn’t include any of the firing or loading mechanisms – it’s just the barrel. Upper receivers can be bought and sold without an FFL license because they’re not considered firearms themselves.
 

 
So to answer your question, no – you don’t need an FFL to buy an upper receiver. However, you will need an FFL to buy a complete firearm (with both the upper and lower receivers assembled). You also need an FFL if you’re going to be buying a firearm from a licensed dealer.

It depends on the state. In some states, you do not need an FFL to own an upper receiver. However, to transfer an upper receiver (or any other firearm) from one person to another, you must have an FFL.
 

 
An FFL is a Federal Firearms License. It is a license that allows you to purchase and sell firearms by federal law. If you do not have an FFL, then you cannot legally purchase or sell firearms – including upper receivers.
If you are interested in obtaining an FFL, please consult your local firearms dealer or the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF).

You only need a Federal Firearms License if you are dealing in firearms as a business. If you are simply buying and selling firearms as a private individual, then you do not need a license.
The same is true for receivers – an upper receiver is just the part of the gun that holds the barrel and bolt assembly. So long as you are not buying and selling them as part of a business, you do not need a license.
