H.B. No. 4451 amends the Texas Penal Code regarding the possession, manufacturing, transporting, repairing, or selling of machine guns. Specifically, it modifies Section 46.05(a)(1) to remove the classification of machine guns as items that require registration in the National Firearms Registration and Transfer Record, while retaining the requirement for explosive weapons and short-barrel firearms. The bill also repeals Section 46.01(9), which previously defined machine guns within the context of the law.

The changes introduced by this bill will only apply to offenses committed on or after its effective date of September 1, 2025. Any offenses that occur before this date will continue to be governed by the existing laws in place at that time.

Statutes affected:
Introduced: Penal Code 46.05, Penal Code 46.01 (Penal Code 46)
