Built to Weatherby’s exacting standards in Italy, the 18i uses a proven inertia operating system to deliver an evenly-weighted gun with superior reliability. Instead of porting off gasses from the combustion like a gas-operated shotgun, this action harnesses the energy of the recoiling gun to run its bolt. Because no powder gets re-routed into the gun, the result is a cleaner-running, low maintenance gun. Designed for shooters who demand consistency of performance for high-volume shooting, the 18i combines engineering and superior material composition to provide reliable operation in the harshest of environments. The one-piece receiver is precision machined from billet aluminum for strength and simplicity. The 18i is shipped with five choke tubes and a proper choke tube wrench.
