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

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

We found no adult SBR possession offense in Idaho Code Title 18, chapter 33. The one place a sawed-off rifle shows up is Idaho Code 18-3302F(2), which bars minors from having one. Federal law still applies, and this page covers both.

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

The short answer

No adult SBR offense found. We read Idaho Code Title 18, chapter 33 (firearms, explosives and other deadly weapons) and found no adult possession offense for an SBR.
Minors are covered. Section 18-3302F(2) bars anyone under 18 from possessing a sawed-off rifle, except as provided by federal law.
Penalty for adults: none found. For a minor with a sawed-off rifle, it is a misdemeanor.
Federal law still applies. See Federal process in 2026 below.

The statute

The only provision we found that names a sawed-off rifle is Idaho Code 18-3302F, titled "Prohibition of possession of certain weapons by a minor." Subsection (2) says:

"Except as provided by federal law, a minor under the age of eighteen (18) years may not possess the following:"
"A sawed-off rifle or sawed-off shotgun; or"
"A full automatic weapon."

This section reaches minors only. We found no SBR provision aimed at adults in the sections we read. Confirm with an attorney if your situation is unusual.

How Idaho defines an SBR

The Idaho statutes we read have no SBR definition, and section 18-3302F doesn't define a sawed-off rifle. Federal law does: under 26 U.S.C. 5845, an SBR is a rifle with a barrel under 16 inches, or a weapon made from a rifle with an overall length under 26 inches.

Penalty

Adults: none found for an SBR in the sections we read.
Minors: subsection (3) says "Any person who violates the provisions of subsection (2) (a) of this section is guilty of a misdemeanor."
Full automatic weapons (minors): subsection (4) makes that a felony, which is separate from SBRs.

Is legality tied to federal registration?

Not for adults, as far as we found, because we found no adult SBR offense to be exempt from. The only federal reference in section 18-3302F(2) is the opening clause, "Except as provided by federal law," and it doesn't mention registration. How that clause applies to a minor with an SBR is Not yet verified.

The Idaho Constitution, Article I, Section 11, says: "No law shall impose licensure, registration or special taxation on the ownership or possession of firearms or ammunition."

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. Our Idaho suppressor guide reports that Attorney General Raúl Labrador's October 12, 2026 release says buyers "still must complete the ATF Form 4473 and a background check," and that the guidance "is an enforcement policy that the ATF says could be reversed."

Hunting

SBR-specific hunting rules: Not yet verified. Per our suppressor guide, Idaho's big game rule, IDAPA 13.01.08, doesn't mention suppressors, and the firearm, scope and any attachments together can't weigh more than 16 pounds.

Other laws that interact

Minors: section 18-3302F(1) says "It shall be unlawful for any person under the age of eighteen (18) years to possess or have in possession any handgun." Subsection (5)(b) defines a handgun by a barrel length that does not exceed twelve inches.
Full automatic weapons: a minor who violates subsection (2)(b) is covered by "Any person who violates the provisions of subsection (2) (b) of this section is guilty of a felony."
Local rules: per our suppressor guide, Idaho Code 18-3302J states the "legislature's intent to wholly occupy the field of firearms regulation within this state," so cities and counties can't regulate firearms.
Manufacturing, CLEO certification and state licensing for SBRs: Not yet verified.

Braced pistols

Section 18-3302F, the statute cited here for SBRs, doesn't mention pistol braces. Idaho Code 18-3315B does list braces among firearm accessories in its definitions, but we haven't verified how Idaho treats a braced pistol as an SBR. See our pistol brace guide.

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.
