The Weatherby 18i series of semi-automatic shotguns are built on the proven inertia system, that provides reliable cycling on an evenly-weighted gun. Boasting classic Weatherby appeal and deadly shoot-ability, the nickel metalwork and high-grade walnut features are an excellent combination that delivers in the field and on the range. Designed and built for shooters that require superior reliability with high volume shooting, the single piece receiver is precision machined from billet aluminum for strength and simplicity.
