Winchester SX4 Field 12ga | 28″ Barrel | MFG# 511210392

The Winchester SX4 Field is a semi-automatic 12-gauge shotgun configured for field use and sporting applications. It pairs a 28-inch back-bored vent rib barrel with a 3-inch chamber and an Active Valve gas system designed to cycle a wide variety of loads. The gun is finished with a satin oil Grade I walnut stock and a matte black aluminum-alloy receiver, and it ships with three Invector-Plus choke tubes (Full, Modified, Improved Cylinder). Built-in ergonomics and the Inflex recoil pad reduce felt recoil and improve follow-through on successive shots.
