SBR between states

[Outlaws]

So if I have a AR lower registered as an SBR, but I have multiple uppers, would it still technically be illegal to take the lower with a 16" or 20" upper to another state that allows normal 16"+ ARs?

I wouldn't take an SBR across state lines without an approved Application to Transport Interstate, regardless of the upper I had attached at the moment.

wdlsguy is right, the lower is still registered as a Title II weapon regardless if it has a 16" upper or a 7" upper on it, or no upper on it.

you need to fill out the form he linked you to and have it approved by NFA.

I have also concerned myself with this question. I would tend to agree with what the other posters have said. Logic would dictate that if the weapon had a 16" barrel then it would not longer be a sbr, thus none of the laws that apply to sbr's would apply, however the receiver is still registered as a sgr. And since when has logic had anything to do with the laws.

It wouldn't hurt to write a letter to BATF. Do you want me to send you 20 cents to cover half the cost of a stamp?

The receiver is the registered device, so if you take the receiver across state lines, it doesn't matter what upper is attached; the receiver is still an SBR.

Thanks. I just wasn't sure how the wording of the registering is since I haven't registered one yet. Ya know, like if its registered so that the reciever can be a SBR at will, or if it is just considered an SBR no matter what.
