The lack of the stock does not change anything. On that count he is completely wrong. It does not become a pistol just because you remove the stock.
He is correct though if you think you can remove the stock and put on a shorter than 16 inch barrel. In that case he is completely right and is what I think he meant. Doing that is making an illegal SBR or AOW.
You cannot take a lower that has ever had a stock attached to it and turn it into a pistol, EVER! You can take the rifle lower and convert it to an SBR or AOW and put a shorter than 16 inch barrel on it but not until you have done a Form 1, paid your $200, and been approved as well as have your name, city, and state engraved on the lower.
I'm sorry I was unclear. This is exactly what I meant to say. Thank you for putting it more eloquently than I did.
