Thinking about building another SBR, 9mm colt lower variety. I know I have to get prints and pics done. How do I go about notifying the CLEO and who is that for Cobb? Sheriff or someone at the Cobb PD? Local precinct? Can I mail it in or do I have to hand deliver? I haven't think about filing for anything in a while so I haven't been keeping up on it. I know I'm going to amend my trust to reflect that I am the sole trustee. Does anyone know if that has worked to get approval?
