Shotgun choke tube

Image Number 3 for United States Patent #6052935.

The present invention relates to a shotgun choke tube including a cylindrical body having an interrupted thread section located on its outside surface. A continuous thread section made up of at least one continuous full thread circumscribing the cylindrical body outside surface is provided adjacent the interrupted thread section. The continuous thread section may comprise between about two and about five continuous threads. The choke tube interrupted threads engage corresponding interrupted threads located on the interior surface of a shotgun barrel muzzle internal surface. The choke tube may be secured in a shotgun barrel with only a fraction of the turns required to secure well-known choke tubes having a long section of continuous threads.
