The Iver Johnson .410 Bore Improved Modified Choke Tube (brand part no. 410IMPMOD) is an extended, stainless steel choke built with Mobil-pattern threads for .410 bore shotguns that use that choke system. The Improved Modified constriction tightens shot patterns further than a Modified choke, making it a strong pick for shooters stretching out on clay targets or small game at longer range. Its extended profile protrudes past the muzzle for easy hand-tightening and quick identification on the range. Note that, per the manufacturer, this choke cannot ship directly to California addresses.
