Iver Johnson 12 Gauge Improved Cylinder Mobil Choke Tube

The Iver Johnson 12 Gauge Improved Cylinder Choke Tube (brand part no. 12GAIMPCYL) opens up the shot pattern for close, fast-moving targets like flushing upland birds or clays thrown at short range. Machined from stainless steel and cut with a Mobil thread pattern, it threads into any Iver Johnson shotgun built for Mobil-style choke tubes. The extended profile leaves a visible portion of the tube past the muzzle, making it easy to identify and remove without a wrench in most cases. An Improved Cylinder constriction is the right call whenever the shot needs to open early for a wider effective pattern.
