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 premium engineering and material composition will provide consistent performance in the harshest of environments. The safety is conveniently located behind the trigger with a positive red ring for visible confirmation when in the "ready to shoot" position. Five choke tubes and a true choke tube wrench are all included and contained in a small plastic case.
