Wisconsin Suppressor Laws in 2026: A Felony With a Federal Exemption

By The Release Desk · Updated · How we verify · Editorial standards

In Wisconsin, possessing a silencer is a Class H felony unless you fit an exemption, and the one most people use is written around the federal NFA's "licensing and registration requirements." ATF stopped requiring that registration on October 9, 2026. Wisconsin's statute didn't change. Here's what that means for buyers and hunters.

Not legal advice. This page summarizes Wisconsin statutes, DNR regulations and federal guidance as of the date above. As far as we found, no Wisconsin court or state official has said how Wis. Stat. 941.298 applies after ATF's change. Talk to your dealer or a Wisconsin attorney before you buy without federal registration.

The short answer

What Wis. Stat. 941.298 says

Subsection (2) is short: "Whoever sells, delivers or possesses a firearm silencer is guilty of a Class H felony." Subsection (3) lists who it doesn't apply to, including law enforcement, the armed forces, licensed manufacturers and dealers, and, in (3)(c), "Any person who has complied with the licensing and registration requirements under 26 USC 5801 to 5872."

The law has held up in court. In State v. Barrett, 2020 WI App 13, the Wisconsin Court of Appeals rejected a Second Amendment challenge to 941.298.

Why ATF's October 9 change doesn't settle it

ATF now says it will not enforce the NFA's approval and registration requirements for suppressors, SBRs, SBSs and AOWs for anyone. Its fact sheet stresses that "State and local laws still apply," and ATF's FAQ says it "cannot opine" on how states treat the change.

Wisconsin's wording makes the gap plain. The exemption isn't "complies with federal law" in general; it's having "complied with the licensing and registration requirements." Buying a can on a 4473 with no registration doesn't do that. A reasonable argument exists that the requirements are unenforceable now, but nobody in Wisconsin government has endorsed it as far as we found.

On October 9, Firearms Policy Coalition sent letters to the attorneys general of 15 states whose laws tie legality to NFA registration, Wisconsin included, asking them to stop enforcing those laws and to seek repeal. We found no public reply from Attorney General Josh Kaul as of this update. A letter isn't a legal opinion, and it doesn't protect anyone charged under 941.298.

What Wisconsin buyers should do now

Hunting with a suppressor in Wisconsin

Wisconsin allows hunting with a suppressor, but DNR's regulation keeps a federal hook. Its weapons and ammunition rules list as illegal: "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." That language predates ATF's change and doesn't describe a 4473-only purchase. A hunter with an approved Form 4 is in the position the rule was written for. One without it is relying on an argument DNR hasn't accepted.

Normal rules still apply: legal firearms and ammunition for the season and zone, plus license, tagging and blaze-orange rules.

Bottom line for Wisconsin buyers

Wisconsin is one of the states where ATF's change helps least until the Legislature acts. Register the can on a $0 Form 4, keep the approval, and you're inside both 941.298 and DNR's hunting rule.

Frequently asked questions

Are suppressors legal in Wisconsin in 2026?
Yes, with a catch. Wis. Stat. 941.298 makes silencer possession a Class H felony unless you've complied with the NFA's licensing and registration requirements. Until Wisconsin changes the law, a $0 voluntary Form 4 is the safe way to fit that exemption.
Does ATF's October 2026 change make unregistered suppressors legal in Wisconsin?
Not clearly. ATF stopped enforcing federal registration, but Wisconsin's exemption requires having complied with the registration requirements. No Wisconsin court or official has said otherwise, as far as we found.
Can you hunt with a suppressor in Wisconsin?
Yes, if you meet DNR's rule, which bars hunting with a suppressor unless the hunter possesses the proper federal firearm license authorizing it. An approved Form 4 is the clearest way to meet it.
What is the penalty for an illegal silencer in Wisconsin?
Selling, delivering or possessing a firearm silencer outside the exemptions is a Class H felony under Wis. Stat. 941.298(2).
