You got more than I did. They redacted the manufacturer on all of my forms. Some only had the date. They also sent me a bunch of blank pages with just the citation of the law that they redacted it under.

No relationship with the seller, just looked like a good deal.
Someone please post a review once you receive it. The OP's post is just a cut and paste from the Amazon ad. I would like to know the number of pages and topics covered before shelling out $50. Thanks!
Some came with factory selectors. The one on the linked M6 looks like it was replaced with a right side selector from an AR15 ambidextrous safety. It is probably just a selector replacement as I doubt someone converted a non-safety M6 to a safety one.
