I know folks have done it with the HK weapons. If you have a registered SP 89 or 94 you can have it changed to say MP5.
So, if I’m going to register a weapon to build a SBR can I first have the name changed from
SA M-7 to AKS-47S or a SA M-5 to AKS-74U
So that the Form1 reads AKS-47S instead of Sa M-7?
but is welding over SA M-7 and re-engraving AKS-47S is OK?
