A firearm choke tube includes a cylindrical body, a choke interrupted thread section, and a locking tab. The choke interrupted thread section is positioned on an outer surface of the cylindrical body and configured to threadably engage an interrupted thread section of a barrel of a firearm to limit longitudinal movement of the cylindrical body relative to the barrel. The locking tab protrudes from the outer surface of the cylindrical body and is configured to interface with a detent formed in the barrel to limit rotational movement of the cylindrical body relative to the barrel. |
