Suppressors, New Hampshire, and Dual Residency:
A Path That Stays in New Hampshire

I live in Massachusetts but also stay regularly in New Hampshire. Can I legally purchase and own a suppressor through my New Hampshire residency?

What Massachusetts Law Says

MGL c. 269, Section 10A^[1] prohibits civilian suppressor possession in Massachusetts even when the item is federally registered. The section contains narrow exemptions for specified manufacturers, authorized law-enforcement use, and certain official training activity. It does not create a general civilian NFA exception.

The Federal Dual-Residency Framework

The ATF's definition of "state of residence" in 27 C.F.R. Section 478.11^[2] explicitly addresses dual residency: "A person can have two states of residence, e.g., a person maintains a home in State X and a home in State Y and resides in both states; then both State X and State Y are states of residence." The regulation gives the direct example of a person who resides in one state during the week and another on weekends, holding that both qualify. No minimum number of days or nights is specified.

An NFA transfer — a suppressor requires a Form 4 submitted through a licensed dealer with a Special Occupational Tax (SOT) endorsement — must be processed in a state where the buyer is a resident. If New Hampshire qualifies as a genuine state of residence, the transfer can be completed in New Hampshire through a NH dealer. Massachusetts residency does not block the NH transfer. The two states coexist.

What Qualifies as Residency

Section 478.11^[2] addresses the student and rented-room scenario directly: "A student residing away from home may or may not be a resident of the State in which he or she attends school." Whether the student qualifies turns on whether they genuinely reside there — not whether they own property. The same principle applies to any person who rents a room, uses a family member's home, or maintains a cabin: genuine occupancy with intent to make the location a home, however periodic, satisfies the definition.

Dual-state residence turns on actual residence during the relevant period, not on obtaining a document solely for a transaction. The transferring FFL and ATF determine what identification and supplemental documentation satisfy federal requirements. A lease, vehicle registration, driver's license, or voter record may be relevant evidence, but none should be described as an automatic residency workaround.

The NFA Transfer Process in New Hampshire

New Hampshire Chapter 159-B concerns shooting-range noise and does not authorize suppressor ownership. New Hampshire does not separately prohibit federally lawful civilian suppressor possession, and 2014 HB 1495 repealed the former hunting-use restriction.^[3] An individual transfer generally requires ATF Form 4 through a New Hampshire FFL/SOT, the required background check, photographs, fingerprints, and CLEO notification. ATF's 2026 final regulatory change reflects a $0 NFA tax for suppressors effective January 1, 2026, while the $200 tax remains for machine guns and destructive devices.^[5] Processing times are operational and should be checked directly with ATF rather than treated as a fixed legal rule.

During the approval period, the suppressor remains at the dealer. After approval, the item transfers to the buyer in New Hampshire.

The Line That Cannot Be Crossed

This is the structural limit of the path. Federal law permits ownership. New Hampshire law permits ownership. Massachusetts law prohibits possession, and that prohibition contains no NFA exception.

The Firearms Owners' Protection Act, 18 U.S.C. Section 926A^[4], provides interstate transit protection when moving a firearm between two places where the person may lawfully possess it. Although a silencer is itself a "firearm" under 18 U.S.C. 921(a)(3)(C), that both-endpoints-lawful requirement is the reason FOPA cannot help here. Because Massachusetts prohibits suppressor possession under Section 10A, Massachusetts can never be a lawful endpoint. A suppressor transported into Massachusetts, even unloaded and locked, is therefore not protected by FOPA and violates Section 10A.

The suppressor must be stored in New Hampshire, used in New Hampshire, and kept in New Hampshire. Any transport across the state line — for any reason, under any storage condition — creates criminal exposure under MGL c. 269, Section 10A.

NFA Trusts Do Not Change This

NFA trusts allow multiple named trustees to possess an NFA item. A Massachusetts resident who forms an NFA trust and lists a NH address does not resolve the state prohibition. If a trustee possesses the suppressor in Massachusetts, that possession violates Section 10A regardless of the trust's structure or registration status. A trust is a transfer vehicle, not a residency workaround.

Bottom Line

Settled: Massachusetts has no general civilian exception for a federally registered suppressor. Federal law can recognize more than one state of residence when the person actually resides in each state during the relevant period. A suppressor is a firearm under federal law, but Section 926A requires lawful possession and carry at both endpoints. Massachusetts therefore cannot be treated as a lawful suppressor endpoint.

Unsettled: No ATF open letter, formal ruling, or First Circuit decision has addressed this precise fact pattern — a MA/NH dual resident purchasing a suppressor in NH. The analysis rests on regulatory text, not a direct precedent.

Do: Establish genuine New Hampshire residence before any transfer, disclose the complete facts to the licensed New Hampshire SOT dealer, and follow the dealer's and ATF's documentation requirements. Keep the suppressor outside Massachusetts. Obtain qualified legal advice before relying on Section 926A for any interstate suppressor transport.
