Under current ghost gun laws in Texas, building or owning an unserialized firearm for your own use is not a crime, provided you are legally allowed to possess a gun in the first place. Texas has no serialization requirement for privately made firearms. The legal danger lies elsewhere: in who you are, where you take the gun, what you build, whether you sell any of them, and whether you cross a state line.
No State Ban on Unserialized Firearms
Roughly sixteen states now require serialization of privately made firearms. Texas is not one of them. Texas Penal Code Chapter 46 regulates who can carry firearms, where they are prohibited, and which weapon types are banned outright, but nothing in that chapter singles out ghost guns or privately made firearms.1State of Texas. Texas Penal Code 46.02 – Unlawful Carrying Weapons Once assembled, a home-built pistol or rifle is treated like any other legal firearm in the state.
The practical result: a Texas resident who is at least 21, has no felony convictions or other disqualifying history, and builds a standard handgun or rifle at home is not violating any Texas statute by keeping that firearm unserialized. That’s a narrower group than many people assume, and everything that follows explains why.
What the 2025 Supreme Court Ruling Changed for Federal Law
In April 2022, the ATF finalized Rule 2021R-05F, expanding the federal definitions of “firearm,” “frame,” and “receiver” to cover partially complete or nonfunctional frames and receivers, along with weapon parts kits that can readily be assembled into a working gun.2Bureau of Alcohol, Tobacco, Firearms and Explosives. Summary of Final Rule 2021R-05F On March 26, 2025, the Supreme Court upheld that rule 7-2 in Bondi v. VanDerStok, holding that the ATF’s definitions are consistent with the Gun Control Act.3Supreme Court of the United States. Bondi v. VanDerStok, No. 23-852
Read carefully, though, the rule leaves individual builders where they were. The ATF’s own overview states that the rule “does not prohibit an individual from making their own” privately made firearm and “does not mandate unlicensed persons mark their own” privately made firearm.4Bureau of Alcohol, Tobacco, Firearms and Explosives. Definition of Frame or Receiver and Identification of Firearms – Overview The serialization mandate attaches to licensed dealers. When a dealer takes a privately made firearm into inventory, the dealer has to mark it within seven days or before transferring it, whichever comes first.5Bureau of Alcohol, Tobacco, Firearms and Explosives. Definition of Frame or Receiver and Identification of Firearms
What did change: unfinished receivers and parts kits sold at retail must now be serialized, and buyers must clear a background check. Bringing your existing ghost gun to a gunsmith for anything beyond same-day repair means the shop has to serialize it before returning it to you.
How a Ghost Gun Turns Into a Criminal Case
The unserialized firearm itself is not the charge. The charge comes from a separate Texas weapons statute that would apply to any gun. Three scenarios cover most of the exposure.
You Are a Prohibited Person
Texas Penal Code Section 46.04 bars certain people from possessing any firearm. A convicted felon caught with a ghost gun faces a third-degree felony, punishable by two to ten years in prison and a fine up to $10,000.6State of Texas. Texas Penal Code 46.04 – Unlawful Possession of Firearm7State of Texas. Texas Penal Code 12.34 – Third Degree Felony Punishment The prohibition runs five years past release from confinement or supervision, whichever ends later. After that, a felon can possess a firearm only on their own premises.
Others fall inside the same section. Someone convicted of a Class A misdemeanor for domestic violence against a family or household member cannot possess a firearm for five years after release. A person under a Texas Family Code protective order cannot possess a firearm while that order is active. Both are Class A misdemeanors, carrying up to one year in county jail and a fine up to $4,000.6State of Texas. Texas Penal Code 46.04 – Unlawful Possession of Firearm8State of Texas. Texas Penal Code 12.21 – Class A Misdemeanor Punishment
Prosecutors often argue that a prohibited person’s choice of an untraceable weapon shows intent to evade the firearms ban, which affects plea negotiations and sentencing even without a separate charge.
You Carry It Into a Prohibited Location
Texas Penal Code Section 46.03 makes it a standalone offense to carry any firearm into certain places, serial number or not. The list includes school premises, polling places during elections, courthouses, secured airport areas, correctional facilities, and bars where at least 51 percent of income comes from on-premises alcohol sales, along with several other locations.9State of Texas. Texas Penal Code 46.03 – Places Weapons Prohibited
Most Section 46.03 violations are third-degree felonies, meaning two to ten years in prison and a potential $10,000 fine.7State of Texas. Texas Penal Code 12.34 – Third Degree Felony Punishment A few of the listed locations carry a Class A misdemeanor instead, such as hospital premises and sporting events.9State of Texas. Texas Penal Code 46.03 – Places Weapons Prohibited The grade depends on the subsection, not the kind of firearm.
You Build a Prohibited Weapon Type
If your build qualifies as a prohibited weapon under Texas Penal Code Section 46.05, it’s a third-degree felony. The banned list includes machine guns, explosive weapons, and zip guns, unless the item is properly registered in the National Firearms Registration and Transfer Record.10State of Texas. Texas Penal Code 46.05 – Prohibited Weapons This is where home builds most often go wrong. Machine a rifle barrel below 16 inches or a shotgun barrel below 18 inches, and you have created a short-barreled rifle or shotgun that falls under the National Firearms Act. Federal law requires you to file ATF Form 1 and receive approval before making an NFA firearm.11Bureau of Alcohol, Tobacco, Firearms, and Explosives. Application to Make and Register NFA Firearm – ATF Form 5320.1 Possessing an unregistered NFA firearm is a federal felony carrying up to ten years in prison.
Selling What You Build
Texas law lets you make a firearm for your own use. The moment you sell, barter, or transfer ghost guns for profit, federal law treats you as someone “engaged in the business” of dealing or manufacturing firearms. After the Bipartisan Safer Communities Act, the ATF broadened that definition to reach anyone intending to “predominantly earn a profit” from firearm sales, even as a side pursuit. Dealing without a federal firearms license carries up to five years in federal prison and a fine of up to $250,000, and any firearms involved are subject to seizure.12Bureau of Alcohol, Tobacco, Firearms and Explosives. Do I Need a License to Buy and Sell Firearms? – ATF Guidance
Texas layers its own transfer restrictions on top. Under Section 46.06, selling or giving a firearm to a person under 18, to someone intoxicated, or to a known felon within five years of release is a separate state offense.13State of Texas. Texas Penal Code 46.06 – Unlawful Transfer of Certain Weapons The absence of a serial number does not exempt a ghost gun from any of these rules.
Never-Serialized Is Not the Same as Serial Removed
This distinction matters. Owning a firearm that was never serialized is a different act from removing or altering a serial number on a firearm that had one. Federal law under 18 U.S.C. § 922(k) makes it illegal to possess, transport, or receive a firearm whose serial number has been removed or obliterated, provided the firearm has moved in interstate commerce.14Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts The penalty is up to five years in federal prison.15Office of the Law Revision Counsel. 18 USC 924 – Penalties
Texas has its own version in Penal Code Section 31.11, a Class A misdemeanor that reaches anyone who knowingly removes, alters, or obliterates a serial number on tangible personal property, or possesses property knowing the number has been tampered with.16State of Texas. Texas Penal Code 31.11 – Tampering With Identification Numbers That statute only reaches property where a serial number existed to begin with. A firearm you built from scratch that never bore a manufacturer’s number does not fall under either provision. Grind the number off a factory pistol, and both statutes apply.
Using a Ghost Gun in Another Crime
Any firearm used during another offense triggers enhanced penalties. Federal law adds a mandatory five years to the sentence for using or carrying a firearm during a crime of violence or drug trafficking offense, with a seven-year floor for brandishing and ten years for discharging. These sentences run consecutively to the underlying crime’s sentence.15Office of the Law Revision Counsel. 18 USC 924 – Penalties Prosecutors use these provisions aggressively because judges cannot reduce them or grant probation.
In state cases, Texas treats a firearm used during a felony as an aggravating factor that can raise the punishment range. The lack of a serial number does not create a separate enhancement, but it does give investigators and prosecutors additional questions about how and why the defendant obtained an untraceable weapon.
Taking a Ghost Gun Out of Texas
Texas’s permissive approach stops at the state line. At least sixteen states regulate ghost guns through serialization requirements, background checks on parts, or outright possession bans. California, New York, New Jersey, and Illinois all require serialization of privately made firearms and impose criminal penalties for noncompliance.17Bureau of Alcohol, Tobacco, Firearms and Explosives. Privately Made Firearms
Federal law does not specifically ban carrying a privately made firearm across state lines if it is legal at both ends of the trip. The federal Peaceable Journey provision under 18 U.S.C. § 926A protects travelers passing through restrictive states when the firearm is legal at the origin and destination. That protection is narrow and gets tested in court often. Driving through a state that bans unserialized handguns, even on the way to one that allows them, is the kind of situation where you may end up explaining the federal safe-passage law to a local officer who reads it differently.
For most Texas owners, the ghost gun itself is not the risk. The risk is stacking it onto another violation: a felon who keeps one at a friend’s house, a permit holder who forgets it is in the bag at a courthouse, a hobbyist who sells a few builds online without a license. Each of those turns a legal object into evidence, and the penalties do not soften because the gun was made at home.
