Thanks for the advice. I'm trying to get as much filed as I can before July gets here. I am waiting for my MPX and my Aero lower's tax stamps to get back. I am debating on getting a suppressor or two.
No problem. The good news is once the lower is SBR'd you're home-free. You don't even want to buy an upper for it yet anyway. Go ahead and get your stamps and then buy your upper later.
