From my understanding, The form 1 is to “Make” the firearm in it’s “First” caliber. I do not know of an AR with multiple barrels all firing at the same time from the same receiver. It would make a very weird looking quad rail. You would only need to relist (update) the caliber if you were unable to return it to the original configuration. An an example would be if the firearm was made as a 5.56 (HK 53 as an example), had a barrel replaced, and pressed and pinned into the trunnion (Say 300 blackout). You could no longer easily convert it back to 5.56. As long as you can “easily” return it (barrel swap) to the description on the form, you should be OK. So, never get rid of the “First” barrel on your SBR.
As for policy, A lot of the framework for this comes from the United States v. Thompson/Center Arms Co. case in what makes a SBR and conversions.
