Short-barreled rifles are legal to own in Texas. The state removed SBRs from its prohibited weapons list, so there is no state-level criminal penalty for possessing one, but federal law still requires you to register the firearm with the ATF under the National Firearms Act before you build or buy it. Skip the federal step and you commit a federal felony, regardless of what Texas allows.
Texas No Longer Prohibits Short-Barreled Rifles
An older version of Texas Penal Code Section 46.05 grouped short-barreled firearms with machine guns and explosive devices on the state’s prohibited weapons list, and NFA registration only worked as a defense to prosecution.1Justia. Texas Penal Code Chapter 46 – Weapons The current statute drops SBRs entirely. Section 46.05 now lists explosive weapons, machine guns (unless NFA-registered), armor-piercing ammunition, chemical dispensing devices, zip guns, tire deflation devices, and improvised explosive devices, with no mention of short-barreled rifles.2State of Texas. Texas Penal Code Section 46.05 – Prohibited Weapons
The practical effect: compliance is a federal question in Texas. The state creates no extra hoop, but it also cannot shield you from federal enforcement if you skip NFA registration.
What Counts as an SBR
Federal law defines a short-barreled rifle as a rifle with one or more barrels shorter than 16 inches, or any weapon made from a rifle with an overall length under 26 inches.3Legal Information Institute. 18 USC 921(a)(8) – Definition of Short-Barreled Rifle Barrel length is measured from the closed bolt face to the muzzle end. Overall length is measured with any folding or collapsible stock fully extended.
The measurements matter. A rifle that misses either threshold by a fraction of an inch is an SBR, and an unregistered SBR is an unregistered NFA firearm.
Federal Registration Under the NFA
Every SBR has to be entered in the National Firearms Registration and Transfer Record kept by the ATF.4Bureau of Alcohol, Tobacco, Firearms and Explosives. National Firearms Act (NFA) You file an application, submit fingerprints on FBI Form FD-258 and a 2-by-2-inch passport-style photograph taken within the prior six months, and wait for approval after a federal background check. Under the current transfer tax statute, the tax on transferring an SBR is $0; the $200 rate now applies only to machine guns and destructive devices.5Office of the Law Revision Counsel. 26 USC 5811 – Transfer Tax The registration itself is still mandatory.
Possessing an NFA firearm that is not registered to you is a federal crime under 26 U.S.C. ยง 5861.6Office of the Law Revision Counsel. 26 USC 5861 – Prohibited Acts A conviction can bring a fine of up to $10,000, up to ten years in prison, or both.7Office of the Law Revision Counsel. 26 USC 5871 – Penalties
Building One From a Rifle You Own (Form 1)
Converting an existing rifle into an SBR by installing a shorter barrel means filing ATF Form 1, the “Application to Make and Register a Firearm.”8Bureau of Alcohol, Tobacco, Firearms, and Explosives. ATF Form 5320.1 (Form 1) – Application to Make and Register NFA Firearm You can submit through the ATF eForms system or mail paper copies to the NFA Division. Do not shorten the barrel or assemble the SBR until approval comes through. Keeping an unregistered short barrel and a compatible receiver together can create a constructive possession problem even before assembly.
Buying an Existing SBR (Form 4)
Purchasing an SBR already registered to someone else runs through ATF Form 4, the “Application for Tax Paid Transfer and Registration of Firearm.” You provide fingerprints and a photograph, the ATF approves the transfer, and only then can the dealer release the firearm to you.9Office of the Law Revision Counsel. 26 USC 5812 – Transfers Form 4 also files through eForms.
How Long Approval Takes
As of January 2026, the ATF reports average eForms processing times of 14 days for Form 1 and 10 to 11 days for Form 4. Paper submissions run longer: 38 days for Form 1 and 24 to 28 days for Form 4.10ATF. Current Processing Times Those figures assume a correctly completed application. Mistakes add delay.
Engraving Requirements if You Build It
An SBR built under a Form 1 has to be permanently marked. Federal regulations require your name and the city and state where you made the firearm, plus a unique serial number, on the frame or receiver.11ATF eRegulations. 27 CFR 479.102 – Identification of Firearms The serial number, caliber, and model also have to appear on the barrel or frame. Markings must be engraved, cast, or stamped to a minimum depth of .003 inches, with the serial number no smaller than 1/16 of an inch.12ATF eRegulations. 27 CFR 478.92 – Identification of Firearms and Armor Piercing Ammunition They must be conspicuous and hard to remove.
Most builders use a professional engraving service. Home methods often miss the depth tolerance. Engraving is not required when you buy an existing SBR on a Form 4, because the maker already marked it.
Individual Registration vs. an NFA Trust
Register an SBR as an individual and only you can legally possess it. Nobody else can handle, transport, or store the firearm outside your presence. In a shared household with a common gun safe, that is a real constraint.
An NFA trust is a legal entity that holds the registration in place of an individual. Multiple trustees can be authorized to possess and use trust-held items. Every trustee who qualifies as a “responsible person” has to submit fingerprints and a photograph, so the background check reaches everyone with access. Trusts typically run $60 to $500 depending on whether you use a template service or hire an attorney. If a spouse or shooting partner needs independent access, a trust is worth the money.
Storage and Constructive Possession
Only the registered owner, or a trustee of an NFA trust that holds the registration, can legally possess the firearm. If you store an SBR somewhere another person can reach it without you, that person can end up on the wrong side of a constructive possession analysis under federal law. A safe only you can open solves this cleanly.
Taking It Out of Texas
Interstate travel with an SBR requires advance ATF authorization. Federal law prohibits transporting a short-barreled rifle across state lines without approval from the Attorney General, which in practice means filing ATF Form 5320.20 before the trip.13Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts You submit two copies to the NFA Division by mail, fax, or email, and the approval covers only the dates on the form.14Bureau of Alcohol, Tobacco, Firearms and Explosives. ATF Form 5320.20 – Application to Transport Interstate Also check the destination state. Not every state allows SBR possession, and arriving in one that doesn’t creates both state and federal problems.
A change of address, even within Texas, requires written notification to the NFA Division.15Bureau of Alcohol, Tobacco, Firearms, and Explosives. ATF Form 5320.4 – Application to Transfer and Register NFA Firearm A permanent move to another state combines that notification with a Form 5320.20 transport authorization.
Age Requirements
The Gun Control Act sets a minimum age of 21 to buy any NFA firearm, including an SBR, from a licensed dealer. Federal law lets someone at least 18 make an NFA firearm on a Form 1, provided they are not otherwise prohibited from possessing firearms and already legally own the lower receiver being used. Texas adds no separate age rule.
