http://www.atf.gov/alcohol/info/revrule/rules/atf_ruling2005-4.pdfMaking of a silencer by an unlicensed person for personal use does not require
any license or notification to ATF under the GCA. However, under the NFA the
making of a silencer must be approved in advance by ATF. Unlicensed persons
must file an ATF Form 1, Application to Make a Firearm, pay a $200 making tax,
and comply with all other provisions of the law prior to making the firearm.
Approval of the Form 1 results in registration of the silencer to the maker.
Subsequent transfers of the registered silencer must be approved in advance by
ATF. Possession of a silencer not registered to the possessor, and a making or
transfer that does not comply with the NFA and regulations are punishable by
imprisonment for up to 10 years, a fine of $250,000, or both.
