Relating to the unlawful acquisition, purchase, and transfer of certain weapons; creating a criminal offense; increasing a criminal penalty.

HB 2606 creates a new criminal offense for individuals under 21 years old who knowingly possess certain firearms defined as "assault weapons." The bill defines assault weapons by specific features, such as detachable magazines, pistol grips, folding stocks, or capacity to hold more than 10 rounds. Possessing these weapons as a person under 21 would be classified as a state jail felony. Exceptions include lawful possession by peace officers or for weapons owned before August 31, 2025. The law directly affects young adults in Texas who own or acquire these specific firearms.
