The Iver Johnson extended choke tube (brand part no. 12GAEEXTFULL) delivers an extra full constriction for 12 gauge shotguns using the Mobil thread pattern. Built from steel, the extended profile projects beyond the muzzle, which makes the tube easier to identify and remove by hand compared to a flush-mount design, while the tighter extra-full constriction concentrates the shot pattern for longer-range work. This choke suits turkey hunters and waterfowlers who want maximum pattern density at extended range on Mobil-pattern shotguns.
