The Iver Johnson 12 Gauge Improved Modified Choke Tube (brand part no. 12GAIMPMOD) delivers a tighter-than-modified pattern for extended range, built for pass-shooting waterfowl and longer-range clays. 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. A Improved Modified constriction is the right call whenever your shooting calls for pass-shooting waterfowl and longer-range clays.
