    摘要: An automatic shotgun choke is provided which is attached to the muzzle of a shotgun barrel and can be adjusted manually by a device mounted within and extending from upper portion of the choke so as to selectively produce a choked and unchoked muzzle. In a modification gas pressure from a fired shell turns fan blades within the choke to operate a choking action upon a charge as it leaves the muzzle.
