FWIW when my daughter was working in DC, they had one of those humonguous bills come up for vote that was cobbled together at the last minute. It was called an education bill if I recall correctly, many thousands of pages long. Her boss divvied up the bill among people who worked for him, and had each one read a specific number of pages (300 apiece?) and note anything of interest to their outfit.

My daughter said, “Dad, you would not believe what is in that bill. One line on gun control buried in the middle, two lines that basically banned private and home schools, a bit about beef cattle... all buried in thousands of pages of education legalese.”

Once they found the bad bits, they went after congressmen to get them removed before the vote, successfully.

Surely the NRA has such a team to actually read such bills, even if it takes all night the night before the vote.
