I plan to SBR my AR. I have an existing Trust on a pistol suppressor. I know I can use the existing Trust and just add the SBR rifle to it. I do have several questions: 1. I recently moved do I have to form 5320.20 for my suppressor (The form only indicate SBR, MGs and firearms)? 2. On my trust can I use quicken to make amendment? 3. Should the amendment be notarized? 4. When submitting a copy of my old trust should I notarize the Declaration of trust and Ceritfication of trust again? or a xerox copy is good with form 1?
