Somewhat. Not a contiguous document as gun laws are ludicrously complex in the US.

I’d say a great place to start however is the NRA ILA’s “database” of gun laws per state:

The thing to keep in mind is the dichotomy between state and federal laws. Some laws are federal, meaning all states must follow. Then state laws are essentially “above and beyond” federal laws, placing additional restrictions on gun owners/buyers the feds have not. Some states, such as New Hampshire or Montana, have virtually no state level gun laws, thus nothing above and beyond federal ones.

All states will require you to fill out a form 4473 when buying a gun from a FFL, then require a background check, and have certain prohibitions against felons, domestic abusers, and drug users from buying guns.

There is a certain procedure for buying NFA items (machine guns, suppressors, SBRs, SBS), federally imposed. Some states totally ban all NFA items, so these laws don’t matter. Others ban some but not all, and others have no limitations on them (beyond federal limitations).

In addition there are resources out there in carrying concealed handguns. Some states let you carry openly, some states require the gun be concealed. Some states require a permit for all carrying, some require a permit to carry concealed but do not require a permit to carry openly, and some states have no permit requirement for anything. And further there are different restrictions for where and when you can carry that vary dramatically by state.

A good resource for that would be:

Hopefully that helps get you started. I’ve found that even the above sites aren’t always 100% correct though. So even then verify these yourself. Guns laws are insanely complex in the US.
