I always wondered why the ATF chose the lower to make 80% and not the upper. the upper is where the skill comes in to finish.

Because few items have both uppers and lowers.

Exactly, you would think they would have chose the harder of the two if they wanted to keep people from circumventing the law. Since the upper is closer to the chamber, that would be the more likely part to me at least. Not that I’m complaining mind you, just curious how it came to be is all.
