I do have a specific interest but that's all it is at this point. I own no NFA items and have no firsthand knowledge of the processes. Accordingly, I am indeed largely ignorant on the topic. But in my defense, it is not as if the laws and procedures are exactly simple or easy to comprehend. Not to mention, the one very specific question that I came here to ask is new ground to everyone. Yes, there are tons of threads and info on this specific topic and while I had found the same question in my searching, I had yet to find a real answer. To stress the level of misinformation, misunderstanding, and misconceptions, even my LGS gave me a different answer than what I received here.
I appreciate your thorough and kind reply this time around. If it concerns you, I would point out that if you had responded that way to begin with (instead of calling me a liar), I would not have taken offense. Just because you deem something "curious and unlikely" does not automatically make you right.
To clarify a point in your last statement, I never said anything about wanting to acquire a "braced pistol". That was never my goal nor what this thread was about. My question was about buying an AR pistol (which in itself is still entirely legal) and whether or not the ATF's tax stamp waiver would apply to any AR pistol to SBR application during the given forbearance period. As stated, I have received my answer.
