Ghost Gun and 3D-Printed Gun Attorney in Jersey City & Hudson County
Reviewed by William A. Proetta, Esq. · Updated
New Jersey punishes ghost guns more heavily than most states. Simply possessing a firearm built on a frame or receiver without a registered serial number is a third-degree crime under N.J.S.A. 2C:39-3(n). Buying an unserialized frame, receiver or parts kit to build a gun, using a 3D printer to make a firearm or component, and transporting or selling an unserialized gun are second-degree crimes under 2C:39-9(k) through (n), each carrying five to ten years in prison. Since January 2026, even possessing 3D printing files with intent to make a gun is a crime. Ghost gun cases from Jersey City are prosecuted in the Hudson County Superior Court at the Frank J. Guarini Justice Complex near Journal Square. William Proetta Criminal Law defends people charged with ghost gun, 80% receiver and 3D printing offenses from our Jersey City office, with over 15 years of criminal trial experience.

What Counts as a Ghost Gun
The statutes focus on the frame or receiver, the part of a firearm that houses its internal components. New Jersey’s definition reaches not only a finished frame or receiver but any part that can readily be made into one by milling or other means, which covers the 80 percent lowers and polymer pistol frames sold online, as well as complete kits. A firearm built from one of those parts, without a serial number from a federally licensed manufacturer, is unserialized. A 3D-printed frame is treated the same way. The definitions are broad on purpose, but whether a particular piece of plastic or aluminum was readily convertible is a factual question that can be contested with expert testimony.
Penalties and How Ghost Gun Charges Stack
Possession under 2C:39-3(n) carries three to five years and a fine of up to $15,000. The manufacturing, buying, printing and transport offenses are second degree, with five to ten years, a fine of up to $150,000 and a presumption of imprisonment. The legislature raised those offenses from third to second degree in 2022 (P.L.2022, c.53). The parts-purchase offense in 2C:39-9(k) also contains a non-merger clause, so it is sentenced separately even if the same gun produces other convictions. The ghost gun subsections are not on the Graves Act list, but a ghost handgun carried outside the home is almost always charged under 2C:39-5(b)(1) as well, and that count brings the Graves Act parole bar with it.
3D Printers and Digital Files
New Jersey regulates both the printing and the files. Using a 3D printer to produce a firearm, receiver, magazine or firearm component is second degree under 2C:39-9(l)(1), and distributing printable gun files to someone in New Jersey who is not a licensed or registered manufacturer is second degree under (l)(2). A law approved on January 12, 2026 (P.L.2025, c.255) added 2C:39-3(o), which makes it a fourth-degree crime for an unlicensed person to knowingly possess firearm digital instructions with the intent to manufacture a firearm. The intent element is central to any defense of a file case, since many people download files out of curiosity or for lawful reasons. The federal appeals court in Philadelphia affirmed the dismissal of a constitutional challenge to the distribution law in Defense Distributed v. Attorney General of New Jersey, No. 23-3058 (3d Cir. Feb. 12, 2026), and the law remains enforceable while further review is sought.
The Federal Side
Ghost gun cases can also draw federal attention. The ATF’s 2022 rule treats many partially complete frames, receivers and parts kits as firearms under federal law, and the Supreme Court rejected a facial challenge to that rule in Bondi v. VanDerStok, 604 U.S. 458 (2025). Litigation over the rule continues in lower federal courts, but none of it affects New Jersey’s own ghost gun statutes. Federal agencies such as the ATF can become involved in parts-kit and printing investigations, and a case that involves interstate sales or multiple guns can be referred for federal prosecution. Knowing early whether a federal referral is in play shapes every decision in the state case.
How Ghost Gun Cases Start in Hudson County
Ghost gun investigations in Jersey City and Bayonne can begin with records of online parts purchases or packages shipped to an apartment, followed by a search warrant. Others begin when a handgun recovered after a street stop in Jersey City or Union City turns out to have no serial number, and investigators work backward to where the parts came from. In Hoboken and Kearny, a 3D printer seen during an unrelated search, or files found on a seized phone or computer, can add printing and file charges to the case. See our Jersey City gun charges page and our court guides for Jersey City, Hoboken, Kearny, Union City and Bayonne.
Arrest and Pretrial Release
Because the manufacturing and transport counts are second degree and often filed alongside a Graves handgun charge, ghost gun arrests usually proceed on a complaint-warrant, and prosecutors frequently move for detention when several guns or a printer are recovered. A person charged only with possessing files or a single unserialized firearm kept at home has stronger arguments for release. See our pretrial release and detention guide and our page on Central Judicial Processing in Hudson County.
Immigration Consequences
A ghost gun is a firearm under federal law, so a conviction for possessing, building or selling one can trigger the firearms deportation ground. File and distribution offenses that do not involve an actual gun raise different questions for immigration counsel. A plea to a non-firearm offense, or careful drafting of the factual basis, may be necessary to protect a noncitizen client. We review the immigration side before any plea; see our immigration consequences and immigration-safe plea strategy pages.
Defenses in Ghost Gun Cases
- Not a frame or receiver. The State must show the part could readily be made into a working frame or receiver. Incomplete parts, unrelated components and failed prints may not qualify.
- No purpose to build. The parts-purchase offense requires a purpose to assemble a working gun, and the new file offense requires intent to manufacture one. Parts or files held with no plan to build a firearm, for example by a collector, may fall outside those elements. A hobby build does not.
- Serial number issues. A frame or receiver that carries a serial number registered with a federally licensed manufacturer falls outside 2C:39-3(n), even if the rest of the gun was assembled at home.
- Possession. Parts shipped to a shared address, a printer in a roommate’s room or files on a family computer do not prove who possessed them.
- The warrant. Many of these cases depend on search warrants built from purchase records, and the probable cause behind them can be challenged.
