No paperwork of any kind on a barrel in the U.S. Other countries have different laws (Germany for instance requires barrels to be serial numbered and registered).
Lots of folks buy those old cutoffs and turn them into black powder cannons and custom shotgun slug barrels. Having the barrel isn't any more illegal than having a length of the same size iron pipe. If it's used on a cartridge gun designed for one single projectile like a bullet, it's a "destructive device"....but if it's used on a gun designed for shot ie a shotgun receiver, it's perfectly fine.
It is classified as a destructive device by the BATF. You will need the tax stamp, and you will need to look into your state's laws to see what they allow.
---Just the barrel itself won't be a problem. As long as you don't have a receiver lying around, etc. etc.
