Hearing Protection Act of 201 7 This bill amends the Internal Revenue Code to: (1) eliminate the $200 transfer tax on firearm silencers, and (2) treat any person who acquires or possesses a firearm silencer as meeting any registration or licensing requirements of the National Firearms Act with respect to such silencer. Any person who pays a transfer tax on a silencer after January 9, 2017, may receive a refund of such tax. The bill amends the federal criminal code to preempt state or local laws that tax or regulate firearm silencers.
