That was my understanding as well, hence the reason for the 10.5" on mine

Well, I don't know who my examiner is, because I haven't filled out the Form 4 yet. The gun (a 6921) hasn't arrived at my dealer yet. I was hoping to get a 10.5-11.5" upper to go with it, as a kit, and swap back and forth between the two uppers as I desired. Kind of like the original idea between the CQBR upper paired with an M4.
Does notification mean a new Form 1 and engraving the gun or just an official sounding letter?
Thanks guys!
Go to the source. There is no need for any letter if the length or caliber change is temporary. You can put a 10.5" barrel on your SBR even if it was registered with a 14.5" barrel length, if the change is permanent you should send the ATF a letter with the change.
Q: May the short barrel on an SBR or SBS be replaced with a long barrel for hunting or other purposes, with the intent of replacing the short barrel?
A: Yes, and you will not be required to again register the firearm before replacing the short barrel. ATF recommends written notification to the NFA Branch when a firearm’s configuration is permanently changed or removed from the purview of the NFA.
