摘要： 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.
摘要翻译： 用于霰弹枪的图案控制系统和制造系统的方法，其中一个或多个扼流器附件可拆卸地安装在霰弹枪筒和枪管孔的枪口端上，以及一个或多个逐渐减小的扼流圈， 同时形成扼流器附件或单独的附件，以消除扼流器连接孔收缩部和筒孔之间的容限积累。 通过添加或删除扼流器附件，可以实现阻塞收缩，其将在距离霰弹枪的枪口的选定距离处提供期望的图案颗粒密度。

摘要： An adjustable sighting means for a firearm which a shooter can adjust to give the desired point of impact. An elongated rib is adjustably mounted on the gun barrel. The rib can be adjusted in the vertical direction so that the forward end of the rib has a greater vertical movement than the rear end of the rib. The effective pivot point of the rib is to the rear of the rib at a theoretical point which remains constant and is selected to be the position of an average shooter's eye when in shooting position.
