Kansas Suppressor Laws in 2026: The State Offense Is Gone

By Cole Harlan, Editor · The Release Desk · Updated Oct 21, 2026 · How we verify · Editorial standards

Kansas did what most states haven't: it took suppressors out of its criminal code. HB 2501, signed in April 2026, struck the suppressor offense from K.S.A. 21-6301, so Kansas law no longer depends on federal NFA registration at all. Combined with ATF's October 9, 2026 decision to stop enforcing NFA registration, that makes Kansas one of the simplest states to buy a suppressor in. Here's what changed, what didn't, and what Kansas hunters need to know.

Not legal advice. This page summarizes the 2026 Session Laws of Kansas, the Kansas statutes and wildlife regulations, and federal guidance as of the date above. ATF's change is a non-enforcement policy, not a repeal of the National Firearms Act. Ask your dealer or a Kansas attorney if your situation is unusual.

The short answer

Suppressors are legal in Kansas, with no state registration tie. Senate Substitute for HB 2501 (2026 Session Laws of Kansas, chapter 101) removed "the criminal prohibition against firearm suppressors" from K.S.A. 21-6301.
It's in effect. The act was approved April 9, 2026 and took effect on publication in the statute book, July 1, 2026.
Misuse got tougher. The same act raises the sentence one severity level when a suppressor-equipped firearm is used in a nonperson felony or a drug felony.
Hunting is allowed. K.S.A. 32-1002 protects a person who "lawfully possesses" a suppressor and uses it in lawful hunting, and the big game regulation says "Firearm report-suppressing devices may be used."
Federal basics still apply: a Form 4473, a background check, an in-state dealer and age 21 to buy from a dealer.

What HB 2501 changed

Before July 1, 2026, K.S.A. 21-6301(a)(4) made it a crime to possess "any device or attachment of any kind designed, used or intended for use in suppressing the report of any firearm." The law exempted anyone "in compliance with the national firearms act," plus suppressors that qualified as Kansas-made firearm accessories. In other words, a Kansas suppressor owner's legal protection used to be federal registration.

HB 2501 struck subsection (a)(4) entirely and removed it from the NFA-compliance exemption and the Kansas-made exemption. With no state suppressor offense left, there's no state law for an unregistered can to violate. That's why Kansas sits in our "no state registration tie" group, while states such as Missouri and Colorado still have one.

One practical note: when we checked on October 21, 2026, the Legislature's online page for K.S.A. 21-6301 still showed the pre-2026 text. The session law published by the Secretary of State is the enacted text, and it controls.

The act also amended the sentencing statutes. Under the new language in K.S.A. 21-6804 and 21-6805, when a firearm is used to commit a nonperson felony or a drug felony and the trier of fact finds beyond a reasonable doubt that it was "equipped with a device designed to suppress the report of the firearm," the sentence is one severity level higher. A later 2026 act, chapter 155 (HB 2029), reconciled chapter 101's version of 21-6804 with other 2026 amendments to that section.

How ATF's October 9 change plays out in Kansas

ATF's open letter says it will stop enforcing the NFA's approval, registration and tax-stamp rules for suppressors, SBRs, SBSs and AOWs, and its FAQ notes that "many states do not impose state-level controls on silencers." Since July 1, Kansas is one of them. Kansas was also one of the 15 plaintiff states in Silencer Shop Foundation v. ATF, the case behind ATF's change.

That leaves federal enforcement policy as the only open variable. ATF says enforcement could resume and that unregistered items wouldn't be automatically grandfathered. A voluntary Form 4 costs $0 and protects you if that happens.

Hunting with a suppressor in Kansas

K.S.A. 32-1002(c) says nothing in the wildlife statute prohibits "a person who lawfully possesses a device or attachment of any kind designed, used or intended for use in suppressing the report of any firearm" from using it "in conjunction with lawful hunting, fishing or furharvesting." Kansas Department of Wildlife and Parks regulation K.A.R. 115-4-4(g), on big game equipment, says: "Firearm report-suppressing devices may be used."

The statute's word "lawfully" is the only hook. With no state suppressor offense left, a can is lawfully possessed under Kansas law. If you want no argument at all in the field, a $0 Form 4 approval settles the federal side too. Check KDWP's current regulations for your species and season.

Bottom line for Kansas buyers

Kansas took the state out of the suppressor business, and that's exactly how it should work. Buy from a Kansas dealer on a Form 4473, decide whether a $0 Form 4 is worth it to you, and hunt with it. Kansas has 74,550 registered suppressors, according to ATF registry data obtained by the American Suppressor Association.

Frequently asked questions

Yes. HB 2501 (2026 Session Laws of Kansas, chapter 101) removed the suppressor offense from K.S.A. 21-6301, effective July 1, 2026. Kansas law no longer ties suppressor legality to federal registration. Federal Gun Control Act rules, including the Form 4473 and background check, still apply.

Do I need a Form 4 for a suppressor in Kansas?

No. Since October 9, 2026 ATF hasn't enforced Form 4 approval or registration for suppressors, and Kansas law no longer requires NFA compliance. A voluntary Form 4 is still available at $0 if you want the can in the federal registry.
