The Bureau of Alcohol, Tobacco, Firearms and Explosives’s website in general and library in particular is a treasure trove of information on firearms laws and regulations, much of it downloadable in PDF format. I’ve found the publications on this page quite helpful, especially
the Federal Firearms Regulations Reference Guide,
the Federal Firearms Licensee Quick Reference and Best Practices Guide,
the Best Practices: Transfers of Firearms by Private Sellers, and
The first three are updated occasionally, so check the revision date. The first one is revised annually. The last link, to the AFT National Firearms Act Handbook, is not to a PDF but to webpage because it’s updated regularly. In any case, all of these and more on the AFT’s site a excellent. Enjoy.
