State SBR law

Are short-barreled rifles legal in Wisconsin? (2026)

By Cole Harlan, EditorUpdated Oct 28, 2026How we verifyEditorial standards

Wisconsin bans selling, transporting, buying and possessing a short-barreled rifle, and a violation is a Class H felony. The statute exempts anyone who has complied with the federal NFA licensing and registration requirements, and any firearm that may be lawfully possessed under federal law. How that wording applies to an SBR left unregistered after ATF's October 9, 2026 change is not yet verified.

Not legal advice. This page summarizes Wisconsin statutes and federal guidance as of the date above. Local rules and your own circumstances can matter. Check with your dealer or a Wisconsin attorney if you're unsure.

The short answer

Felony unless an exemption applies. Wis. Stat. 941.28 covers selling, transporting, purchasing, possessing and going armed with an SBR. It is a Class H felony.
The civilian exemption is tied to federal law. Subsection (4) reaches anyone who has complied with the licensing and registration requirements of 26 USC 5801 to 5872, and any firearm that may be lawfully possessed under federal law.
Unregistered SBRs are an open question. We found no Wisconsin court ruling or official guidance on how subsection (4) applies after ATF stopped enforcing registration. Not yet verified.
Federal law still applies. See "Federal process in 2026" below.

The statute

Wis. Stat. 941.28 is titled "Possession of short-barreled shotgun or short-barreled rifle." The key subsections read:

(2) "No person may sell or offer to sell, transport, purchase, possess or go armed with a short-barreled shotgun or short-barreled rifle."

(3) "Any person violating this section is guilty of a Class H felony."

(4) "This section does not apply to the sale, purchase, possession, use or transportation of a short-barreled shotgun or short-barreled rifle to or by any armed forces or national guard personnel in line of duty, any peace officer of the United States or of any political subdivision of the United States or any person who has complied with the licensing and registration requirements under 26 USC 5801 to 5872"

(4) "This section does not apply to the manufacture of short-barreled shotguns or short-barreled rifles for any person or group authorized to possess these weapons."

(4) "The restriction on transportation contained in this section does not apply to common carriers."

(4) "This section shall not apply to any firearm that may be lawfully possessed under federal law"

(4) "any firearm that could have been lawfully registered at the time of the enactment of the national firearms act of 1968."

(5) "Any firearm seized under this section is subject to s. 968.20 (3) and is presumed to be contraband."

How Wisconsin defines an SBR

Wisconsin has its own definition in 941.28(1)(b). A short-barreled rifle is:

"a rifle having one or more barrels having a length of less than 16 inches measured from closed breech or bolt face to muzzle or a rifle having an overall length of less than 26 inches."

That matches the 16-inch barrel and 26-inch overall lines in federal law (26 U.S.C. 5845). The same section covers short-barreled shotguns, with an 18-inch barrel line and the same 26-inch overall line.

Penalty

Subsection (3): "Any person violating this section is guilty of a Class H felony." We haven't verified the prison term or fine range for a Class H felony, so we don't state them here.

Under subsection (5), a firearm seized under the section is presumed to be contraband.

Is legality tied to federal registration?

Yes, in the wording. Subsection (4) exempts "any person who has complied with the licensing and registration requirements under 26 USC 5801 to 5872". It also says the section doesn't apply to "any firearm that may be lawfully possessed under federal law". Those are two separate hooks to federal law.

ATF's October 9, 2026 open letter says it stopped enforcing Form 1 and Form 4 approval and registration for SBRs, SBSs, suppressors and AOWs. Voluntary forms are still processed. Wisconsin's statute didn't change.

The first hook asks whether you complied with licensing and registration requirements. An SBR made or bought with no registration doesn't clearly fit that wording. Whether the second hook helps, since ATF no longer enforces the registration step, is untested. Not yet verified. We found no Wisconsin court ruling or state guidance on SBRs. For suppressors, our guide says it found no public reply from Attorney General Josh Kaul to Firearms Policy Coalition's October 9 letters about state laws tied to NFA registration.

Our Wisconsin suppressor guide walks through the same problem for 941.298, and it points to a voluntary Form 4 or Form 1 as the safest fit for a registration-based exemption. The state license question for SBRs: Not yet verified.

Hunting

SBR-specific hunting rules: Not yet verified. Per our suppressor guide, Wisconsin allows hunting with a suppressor, but DNR's rule keeps a federal hook and bars it unless the hunter has the proper federal firearm license that authorizes possession and use of the device.

Other laws that interact

Short-barreled shotguns sit in the same section and carry the same Class H felony.
Felon in possession: 941.29(1m) makes possessing any firearm a Class G felony if "The person has been convicted of a felony in this state." Section 941.28 also appears in that statute's list of violent felonies.
Suppressors are covered separately under 941.298. See our Wisconsin suppressor guide.
Concealed carry, minors, CLEO sign-off and local rules: Not yet verified for SBRs.

Braced pistols

The state statutes cited here don't mention pistol braces. See our pistol brace guide for the federal picture.

Federal process in 2026

The making and transfer tax on SBRs has been $0 since January 1, 2026.
ATF stopped Form 1 and Form 4 enforcement on October 9. Voluntary forms are still processed. See NFA wait times.
Dealers use a Form 4473 and NICS check. ATF won't enforce 18 U.S.C. 922(b)(4) "Until final rules are issued."
"For now," interstate transport still needs an approved Form 20 (18 U.S.C. 922(a)(4)).
A dealer can't sell where state law forbids it (18 U.S.C. 922(b)(2)).

ATF says there is no automatic grandfathering if enforcement resumes. Full detail is on our SBR rules 2026 page, and you can compare states with the state NFA checker.
