Not a lawyer, not legal advice, take this for what it is worth;
Everything I have read is one legal SBR lower covers multiple uppers. As long as there is a legal path to assemble your gun into a legal configuration, this seems to be the key. |

The lower is what is registered. Once you have the stamp you can swap uppers.

Mudpie is correct: one lower, one Form 1 (based on the upper which has the shortest barrel or results in the shortest OAL if you want to be technically correct).

The Form 1 is based on the specs involved in the initial making, a one-time act. There is no "you can go longer but not shorter" or vice versa regulation. |

Once a lower has been registered (has its ONE tax stamp), you can put ANY upper you want to on it.
The configuration submitted on the Form 1 can be thought of as your "original configuration" for that lower. "Making" a firearm requires that details like caliber, barrel length and overall length be stuck in the NFA database. Changing uppers is not "making", it's just swapping parts. There's an old joke whose punchline goes "with what you have, you can have as many of those as you want." It really does work that way with SBR'd ARs. |

To be clear... That would be any rifle upper. legal to use on a non-SBR. If you have a registered SBR lower, you can use any barrel length AR upper on it, regardless of what it’s called. |

Quote HistoryQuoted: As opposed to what other kind of upper? So called “pistol” uppers are simply AR uppers with a barrel shorter than 16”, meaning they aren’t legal to use on a non-SBR. If you have a registered SBR lower, you can use any barrel length AR upper on it, regardless of what it’s called. |

Big Waylon is absolutely correct. The other caution is that non-AR firearms don't always have the lower as the registered portion of the firearm (e.g. HK type guns). From the OP's description it looks like he is talking about registering an AR type lower.

No...as opposed to a short shotgun upper or DD/launcher upper. |

Any non DD upper, though a "pistol" upper would be legal as well. Any upper that doesn't itself need its own stamp. |

Quote HistoryQuoted:
I don't think a <18" shotgun upper falls into your description (it's non-DD, not a pistol upper, and doesn't require its own stamp)? But it certainly couldn't go onto a lower registered as an SBR. With an SBR registered AR lower receiver, you may use an upper with a rifled barrel regardless of barrel length. DD uppers, integrally suppressed uppers, etc. are special cases requiring their own stamps or not meeting the definition of "rifle" for purposes of a short barrel rifle. Man, it's those details that can trip you up.
