The Weatherby 18i series of semi-automatic shotguns are built on the proven inertia system, that provides reliable cycling on an evenly-weighted gun. 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. The advanced polymer stock has been designed for a seamless fit to the shooter with a soft touch area on the cheek rest and aggressive texture in the palm and foregrip.
