Depends on what was broken and where... If the serial # can remain in tact, then the mfg can record or cut off old baffles etc and weld new ones on... If the serial # gets jacked or the can can't be repaired then yes new paperwork could be required and if not under warranty a new tax from youreading all This, a-question arose. Suppose a suppressor was damaged, worn, etc and the manufacturer deemed it needed to be replaced. Im assuming you'd need another 200$ stamp to replace it. Would ATF also sit on forms as though it was just a new purchase, or would the replacement be treated as a replacement for original. IOW, process faster?
