Are short-barreled rifles legal in New Hampshire? (2026)

By , EditorUpdated How we verifyEditorial standards

We found no short-barreled rifle offense in New Hampshire's firearms statutes. RSA chapter 159 and chapters 159-B through 159-F have no SBR, short-barreled shotgun or machine gun provision. The one barrel-length line we found is in RSA 159:1, which uses 16 inches for pistols and revolvers. Federal rules still apply, and this page covers both.

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

The short answer

The statute

We found no SBR provision in the sections we read. The section that shows what is covered is RSA 159:1, the definition for chapter 159, Pistols and Revolvers:

"Pistol or revolver, as used herein, means any firearm with barrel less than 16 inches in length."

"It does not include antique pistols, gun canes, or revolvers."

This is a definition for the pistol chapter. It is not an SBR ban and it doesn't mention rifles by name. Confirm with an attorney before you build, buy or carry a short-barreled rifle.

How New Hampshire defines an SBR

It doesn't, in the statutes we read. There is no short-barreled rifle definition in RSA chapter 159 or chapters 159-B through 159-F. The federal definition (26 U.S.C. 5845) uses a barrel under 16 inches for a rifle, or a weapon made from a rifle with an overall length under 26 inches.

The state's only nearby line is the 16-inch barrel line in RSA 159:1, which applies to the pistol and revolver chapter. We found no overall-length line in the sections we read.

Penalty

None found. Because we found no state SBR offense, there is no state SBR penalty for us to report. Other firearm penalties in chapter 159 exist, such as the felony rules for convicted felons in RSA 159:3, but they aren't SBR-specific.

Is legality tied to federal registration?

Not in the sections we read. With no state SBR offense, there is no New Hampshire exemption that depends on NFA registration. The only federal reference we found in RSA 159:1 is about antique pistols, which may be owned or transferred by museums, collectors and licensed dealers: "provided such ownership or transfer does not conflict with federal statutes." That sentence is not about SBRs.

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. We found no New Hampshire Attorney General or state police guidance on SBRs, so how state law treats an unregistered SBR is untested and Not yet verified. Our New Hampshire suppressor guide covers the related suppressor questions.

Hunting

SBR-specific hunting rules: Not yet verified. Per our suppressor guide, suppressor hunting has been legal in New Hampshire since RSA 207:4 was repealed effective June 10, 2016.

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

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.
