Hi Guys...new to the thread but long time firearms owner and like all here a very proud supporter of the 2nd ammendment! I have a stag lower and a SBR upper (not attached) that i was going to do the paperwork on to get my stamp. I live in Texas and getting the signatures for the SBR are no problem where i live. My question is this: If i move i understand there are states that do not allow SBRs. Are there states that allow AR-15s but not SBRs? My concern is am better off just getting a 16" upper as i might have more flexibility moving. My understanding is once it is an SBR it is always an SBR and even though I might have a 16" upper on it a state might tell me i can't bring it with me regardless of the upper on it as it is a registered SBR. Thoughts? 2nd question: I know we will need to see what legislation is proposed and have it passed before we know the lay of the land going forward, but during the last ban did you have to present all ARs to register them at the same time? I have another AR with a 16" upper. Was it possible last time to bring the guns in 1 at a time to register? There by using the same upper to register both lowers. Thanks all!
