Frequently Asked Questions

Are suppressors legal to own in the United States?

Suppressors are legal under federal law, but their ownership is restricted by state laws. Eight states currently prohibit suppressor ownership: Hawaii, California, Illinois, New York, Rhode Island, Massachusetts, New Jersey, and Delaware. Always check your local and state regulations.

What is ATF Form 4 used for?

ATF Form 4 is the official application required to transfer ownership of an NFA-regulated item, such as a suppressor, from one party to another. It involves a background check and registration process.

How does owning a suppressor via a trust differ from individual ownership?

Owning a suppressor via a trust allows multiple 'responsible persons' to legally possess the item and can simplify estate planning by avoiding probate. Trust applications require background checks on all listed trustees.

Can I travel across state lines with a suppressor?

Yes, you can travel across state lines with a suppressor, provided it is legal in both the state you are departing from and the state you are traveling to. Unlike other NFA items, a Form 5320.20 is not required for suppressor travel if legal in the destination state.
