Texas unlawful silencer possession — Penal Code § 46.05

Texas unlawful silencer possession is a criminal offense under Penal Code § 46.05. Base conduct is classified as a third-degree felony; enhancements and aggravators can move the punishment range higher. Below: the controlling statute text, the full punishment range, common defense theories, and what to do if you have been charged in Collin, Dallas, Denton, or Tarrant County.

The controlling statute

A firearm silencer (suppressor) is a prohibited weapon under Texas Penal Code § 46.05(a)(6) unless registered with ATF on Form 4 with the $200 tax stamp paid. The Texas statute incorporates the federal NFA definition by reference. Possession of a homemade "solvent trap," 3D-printed suppressor, or oil filter adapted to muffle a firearm — even one that has never been used — is a third-degree felony. Texas's 2021 Suppressor Freedom Act (HB 957) has been blocked by federal injunction.

Classification & punishment range

Elements the State must prove

To convict on a Texas § 46.05(a)(6) charge, the State must prove every element beyond a reasonable doubt:

1. Defendant intentionally or knowingly possessed a firearm silencer
2. The device meets the statutory definition under 18 U.S.C. § 921(a)(24) and Penal Code § 46.01(4)
3. Defendant lacked NFA registration (Form 4 approval) for the device
4. Defendant knew or should have known the item was a silencer

Defense strategies

L and L Law Group, PLLC develops the following defense strategies on every Unlawful Silencer Possession case:

• Valid ATF Form 4 registration with $200 tax stamp paid — § 46.05(c) complete defense
• Item is a solvent-trap kit not yet adapted to function as a silencer (intent and modification matter)
• Item does not meet the statutory definition (mufflers for non-firearm engines, model-rocket components)
• Lack of knowledge — item was discovered in shared vehicle or residence without defendant's awareness
• Federal preemption / Second Amendment as-applied challenge under Bruen
• Fourth Amendment suppression of search exceeding warrant scope

Enhancements & collateral consequences

Concurrent federal prosecution under the National Firearms Act (26 U.S.C. § 5861(d)) is common. Use of an unregistered suppressor during a drug-trafficking or violent crime triggers 18 U.S.C. § 924(c), adding a mandatory 30-year consecutive federal sentence. Manufacturing for sale elevates state exposure under § 46.05 to a second-degree felony in some circumstances.
