Sig Sauer Complete 5.56 Lower

[CZ-75BD]

I been told that Sig Sauer Complete 5.56 complete lower doe's not required to be shipped to FFL, and can be shipped directly to buyer.
Is it mean I can put my existing upper and have a complete rifle?
How is this legal?

It isn't.

The lower has the serial number on it, and it must be transferred to you through a FFL dealer.

That what I asked seller and he said that SIG putting serials on upper.
Seller is a FFL holder, really confused...

In some European countries the upper is considered the rifle, while the lower is just considered a hunk of metal. This will be intersting to know.

It depends on which gun you're talking about. Sig offers both an AR varient in 5.56 and their non-AR derived "Sig 556".

If you're looking at a Sig 556, I believe it is controlled like a FAL, where the upper is serialized and is the "controlled part". The upper would therefore require a transfer if coming from a FFL. The lower for that rifle is not regulated like a firearm (just like the FAL's lower or an AR15 upper) and can be bought without a transfer.

If you're talking about a Sig AR 15 in 5.56, then the lower is the serialized part and needs to be transferred from a FFL while the upper is unregulated.

After a quick search I found that the sig rifle is a different animal, and yes, the lower is NOT the firearm, but it only works with a sig upper, which is the firearm.

Well it make scene than, if it work's only with serialized upper it make no difference where you put the serial for transfer.
