New Hampshire has it's own Firearms Freedom Act pending in the legislature. It goes way further than those passed by Montana and Tennessee. It specifically includes a few things such as "sound suppressors". Also, the last two paragraphs read:

159-E:4 Penalty.
  • I. Any public servant of the State of New Hampshire as defined in RSA 640:2 that enforces or attempts to enforce a act, order, law, statute, rule or regulation of the government of the United States upon a personal firearm, a firearm accessory, or ammunition that is manufactured commercially or privately in New Hampshire and that remains within the State of New Hampshire shall be guilty of a class A misdemeanor.
  • II. Any official, agent, or employee of the government of the United States, or employee of a corporation providing services to the government of the United States that enforces or attempts to enforce a act, order, law, statute, rule or regulation of the government of the United States upon a personal firearm, a firearm accessory, or ammunition that is manufactured commercially or privately in New Hampshire and that remains within the State of New Hampshire shall be guilty of a class B felony.

I think these types of laws are a really good sign of states having become fed up with federal intrusion into areas of states rights and abuse of powers in general.
