Iver Johnson Arms 12 Gauge Improved Cylinder Flush Fit Mobil Choke Tube

The Iver Johnson 12 Gauge Improved Cylinder Mobil Choke Tube is a flush-fit constriction tube designed for shotguns threaded in the popular Beretta/Benelli Mobil pattern. Manufactured from durable steel, this choke delivers the Improved Cylinder constriction for the moderate pattern spread that defines this choke size, allowing the shooter to tune pattern performance for typical upland and field work.

The flush-fit profile sits nearly level with the muzzle, allowing the tube to install cleanly without protruding past the barrel end and to be swapped in or out with a standard choke wrench. Iver Johnson Mobil choke threads drop directly into any barrel cut for the Beretta/Benelli Mobil choke standard, giving shotgun owners an affordable way to vary pattern density for sporting, hunting, and general-purpose applications.
