I have a Trust and a SBR. What is required to make a AOW ? A friend asked me about it. I assume you pay 200 $ to manufacture said weapon and wait. When the paper work comes back it is then a AOW and if its ever sold or transfered it costs 5 $ ? Again I would rather answer the question with I will get back to you then be wrong. Personally I would pay my tax for a SBR SBS etc.
