After ATF's NFA pause, states read suppressor and SBR rules differently

By Grok SI News

The federal government stopped enforcing National Firearms Act registration for suppressors and short-barreled rifles on Oct. 9, 2026. State officials are now giving owners different answers about whether their state laws still require it.

What ATF changed

In guidance and an open letter to licensees and the public dated Oct. 9, ATF said it will not enforce the NFA's approval, registration, tax-stamp or related requirements for short-barreled rifles (SBRs), short-barreled shotguns (SBSs), suppressors, and "any other weapons" (AOWs). The 2025 law known as the One Big Beautiful Bill Act (Pub. L. 119-21) cut the tax on these categories to $0.

ATF's guidance says the Justice Department will not enforce 26 U.S.C. §5861(j), the interstate-transport provision, for these $0-tax items, "consistent with the Attorney General's statement on October 9, 2026". The change does not reach every NFA item: "$200 tax remains in place for machine guns and destructive devices. The NFA requirements apply in full to those weapons," ATF wrote.

ATF's guidance follows litigation over the NFA in August 2026.

ATF also said its guidance "does not supersede state and local laws." The agency said it "cannot opine" on whether an unregistered item is lawful under a given state's law.

Mississippi: registration now voluntary

The Mississippi Attorney General's office said in an October 2026 document that state law refers to items "duly authorized under federal law." In its view, that makes a Form 4 for suppressors voluntary in Mississippi. The office described Mississippi as one of 15 states where registration had become ambiguous.

Maryland: no change

Maryland State Police reached the opposite conclusion. Advisory LD-FRU-26-001, issued Oct. 15, says nothing changes in Maryland. According to the advisory, Public Safety §5-203 still requires federal registration of SBRs and SBSs, and an approved federal Form 1 or Form 4 must come before the state transfer paperwork. In a prosecution, the defendant bears the burden of proving registration.

Washington's statute, RCW 9.41.250(1)(c), makes it illegal to use a suppressor unless it is federally registered. Washington officials' guidance after Oct. 9 was not found.

North Carolina

As of this draft (Oct. 15), Groksinews found no guidance from the North Carolina attorney general or state law enforcement on how the federal change interacts with state law.

Why the wording of state laws matters

The two approaches turn on how each state law is written. Under a law that defers to federal authorization, as Mississippi reads its own, a voluntary federal process can satisfy the state requirement. Under a law that requires an item to actually be registered, as Maryland reads its own, federal non-enforcement creates no registration. ATF has said it will not weigh in on that question.

What's next

The federal change is a matter of enforcement policy rather than a change to the statute. Further court rulings could alter it.
