The Winchester SX4 Waterfowl Hunter 20 Gauge delivers reliable semi-automatic performance for waterfowl hunting with its proven Active Valve gas system and weather-resistant Woodland camo finish. This full-size shotgun handles 3-inch magnum shells through its 28-inch barrel while maintaining fast cycling and consistent ejection.
What Makes This Different
The Active Valve gas system automatically adjusts to different shell lengths and loads without manual intervention, cycling everything from light 2¾-inch loads to heavy 3-inch magnums. The oversized bolt handle and enlarged loading port speed reloads in cold weather conditions. Chrome-plated bore and chamber resist corrosion from wet hunting environments better than standard steel finishes.Key Features
