Another advantage of a pre-ban is that you can build a pre-ban lower into a pistol. Sure, you can do it with a post-ban, but you have to make it less than 50oz which is near impossible without a lightening up the upper receiver a bit like PO does.

Negatory Good buddy. Converting a Rifle into a pistol is a federal No-No, regardless of MFG date...
It had to be constructed as a pistol it's entire life.
Meaning, if it left the factory as an AR pistol, it is OK.
Or, if it began life as a stripped lower, and was assembled into an AR pistol, it's OK. Keep in mind that very very very very few AR's were initally assembled into pistols. So, unless you are 100% sure that yours began life as an AR pistol, you are very likely to get into hot water, since there are so few documented Pre-Ban pistol lowers out there.
Just because it is a pre-ban DOES NOT mean you can asemble it into a pistol. If it began life as a rifle, that means it must stay a rifle.
However, if it began life as a pistol, it can be converted back and forth from a rifle to pistol. Go figure!
