Abstract
A pattern control system for a shotgun and the method of making the system in which one or more choke attachments are detachably mounted on the muzzle end of the shotgun barrel and the barrel bore and one or more progressively reduced choke constrictions, either in the bore and the choke attachments or in the attachments alone, are formed at the same time in order to eliminate tolerance buildup between the choke attachment bore constrictions and the barrel bore. By adding or deleting choke attachments, it is possible to achieve the choke constriction which will provide the desired pattern pellet density at the selected distance from the muzzle of the shotgun.
