Don’t let the handsome look of the Walnut Field fool you. Even though it features an elegant, gloss-finished walnut stock and forearm with cut checkering, it’s still the classic Winchester Speed Pump. You can always count on this dependable 12 gauge — from ducks to pheasants to clay birds. And, because it’s a Speed Pump, it will get the job done fast. The WinChoke® interchangeable choke system is standard and includes Full, Modified and Improved Cylinder choke tubes. Available in 26" and 28" barrel lengths.
