This makes me think I should buy all the parts before I submit the form 1, since know one knows what Mustapha Mond will do by the time it gets approved . If I leave them all in boxes and don't even look at one with a tool in hand is that still constructive intent? I DO like the idea of "pistol" upper, but if I don't have a "pistol" lower built does that still work?

This also opens the can of "what is a pistol" worms that I also haven't got my head wrapped around...AFAIK the lower was listed as "other" when purchased and a stock was never installed...

I've already pinged NFAGuy on most of this, we'll see what the resident guru thinks.
