| Edit: let me rephrase to clear some confusion. form1 was approved a month ago for 10" barrel. I want to replace it with a 10.5" due to reliability. Do I need to notify the atf about the change and sell the 10" barrel? |

You'll need to cut down an 11.5" barrel. You'll most likely also need your gas port opened up. I'd send ADCO an 11.5" barrel and explain.
Problem with cutting down your 10.5" is... If you're barrel threads are standard, they'll be .625" long. If you try to remove 0.5" you'd have your existing threads, the gap at the shoulder, the start of new threads, then another gap at the new shoulder. If re-threading a barrel, you'll typically have to remove at least 0.750" |

Quoted:
I was under the assumption that once the gun was "completed" no notification was required if you altered the barrel length, caliber, etc. on an AR SBR? Thats what I thought as long as you have the original upper to return it to the original configuration. |

You're supposed to build it to the specifications listed on the F1 but after that, you're good. |

Change of Description or Address: The registrant shall notify the NFA Branch, Bureau of Alcohol, Tobacco, Firearms and Explosives, 244 Needy Road, Martinsburg, WV 25405, in writing, of any change to the description of the firearms in item 4, or any change to the address of the registrant.
Send them a letter telling them it's being changed from a 10" to a 10.5" and done |

?? That's exactly what I just told you. This has been hashed out on here repeatedly. ETA: I didn't mean to sound confrontational. But you're right, that thread has the info you're looking for in case anyone else wants to see it. |

Send them a letter telling them it's being changed from a 10" to a 10.5" and done They need to know about permanent changes. Not every change. Again, technically the OP needs to let them know because he hasn't "built" it yet. After that, he can use any upper without contacting them or retaining the original upper/barrel. |

The form1 was approved a month ago but I put down 10" barrel. The barrel ended up being 10.5." Do I need to notify them of this? Or is a half inch not worth noting? 1/2 is irrelvant on an SBR. I round all numbers to nearest whole inch, and would not submit .x" anything.... |

They don't need to know about any changes. Notification is purely voluntary for all configuration changes. |
