I have a registered SBR via efile form 1 for a 10.5" SBR; the lower is built off an Anderson lower; hypothetically...what happens if.....no other changes......I want to sell the Anderson lower (for $10 btw cause it's crap) and replace the registered SBR lower with, let's say, an LMT lower...do I need to restart the whole process or simply transfer the form 1?? I'm assuming my question is false and that the answer is that I have to re-start the process with "each" lower, but hoping the ODT can advice...........
