August 5 NFA Ruling

Updated August 21, 2026

A federal court ruled that the government cannot enforce certain NFA registration requirements against the parties covered by that case. It is not a repeal of the NFA, it is not nationwide, and it does not change state law.

Wisconsin: state law ties lawful possession to federal registration or compliance. The Class H felony does not apply to a person “who has complied with the licensing and registration requirements under 26 USC 5801 to 5872” (Wis. Stat. § 941.298(3)(c)).

Ownership Requirements

To own a suppressor in Wisconsin, you must meet federal requirements:

  • Be 21 years or older to purchase from a dealer (a trustee on a trust can be 18 or older)
  • Be a U.S. citizen or legal permanent resident
  • Be legally allowed to possess firearms
  • Complete ATF Form 4 with fingerprints and photograph
  • Pass FBI background check

Wisconsin does not add a state permit, but state law here depends on federal NFA registration or compliance.

Hunting Regulations

Wisconsin DNR lists suppressor use among illegal hunting acts, with a federal exception: “Use or hunt with a suppressor or silencer, unless the hunter possesses the proper federal firearm license that authorizes possession and use of the device.” A lawfully registered NFA suppressor satisfies that.

The framing is worth understanding. In Wisconsin the hunting regulation itself is the prohibition, and your federal paperwork is the exception to it.

Verify this yourself before you hunt

Hunting rules change by agency action as well as by legislature, and they can change between seasons. This reflects our reading of the sources cited above as of August 21, 2026. Before you take a suppressor into the field, read the current regulations guide from your state wildlife agency and confirm anything you are unsure about with them directly. Do not rely on this page, on a forum post, or on a dealer. The person holding the firearm is the person the warden talks to. This is general information, not legal advice.

State-Specific Notes

Wisconsin allows suppressor ownership under federal guidelines. Hunting with a lawfully registered suppressor is allowed under Wisconsin DNR regulations.

What State Law Actually Says

Wis. Stat. § 941.298(2): “Whoever sells, delivers or possesses a firearm silencer is guilty of a Class H felony.”

The exemption at § 941.298(3)(c) covers “Any person who has complied with the licensing and registration requirements under 26 USC 5801 to 5872.” Wisconsin is one of the few that names registration and licensing together.

Local Rules and Preemption

Wis. Stat. § 66.0409 uses a “no more stringent than” standard rather than a flat bar: a political subdivision may not regulate firearms “unless the ordinance or resolution is the same as or similar to, and no more stringent than, a state statute.” Counties may still tax firearm sales, and cities and villages may restrict discharge.

Wis. Const. art. I, § 25 is one of the newest in the country, created in November 1998. Before then Wisconsin had no state arms provision at all.

Worth Knowing

The one every Wisconsin owner should know: the official statute page carries an annotation recording State v. Barrett, 2020 WI App 13, holding that “[s]ilencers are not ‘arms’ for the purposes of the 2nd amendment” and that § 941.298 is therefore not unconstitutional. That is live, published, adverse precedent in this state.

Key Takeaway

Suppressors are legal in Wisconsin, but state law ties lawful possession to federal NFA registration. Hunting with a lawfully registered suppressor is allowed under Wisconsin DNR regulations.
