A record of substantive changes to NFA History. Each entry explains what was added or clarified; the research date on a page tells you when its legal status was last checked.
Expanded all six chapters and the account of the law’s effects using additional primary records. Added document exhibits, an introduction to the NFA, links between cases and definitions, and publisher and corrections information. The 1934 hearing account now distinguishes the witnesses’ initial objections from their responses to the narrower bill.
Rewrote chapter introductions, timeline entries, case summaries, and supporting pages for clarity. Clarified the Thompson/Center tax-refund case, the machine gun definition, and the difference between the 2026 tax change and enforcement policy.
Published six historical chapters, a timeline, court summaries, a glossary, and a bibliography. Current legal-status research was checked through October 20, 2026.
