Winchester SX4 Waterfowl Hunter 20GA 28" Semi-Auto Shotgun Mossy Oak

The Winchester SX4 Waterfowl Hunter delivers rapid follow-up shots and weather-resistant performance for serious waterfowl hunters. This 20-gauge semi-automatic shotgun combines Winchester's proven Active Valve gas system with specialized waterfowl features for consistent cycling in harsh field conditions.

What Makes This Different

The Active Valve gas system automatically adjusts to different shell lengths and loads, eliminating manual adjustments between light target loads and heavy waterfowl rounds. The oversized bolt handle and controls remain operable with gloves, while the synthetic stock resists warping in wet conditions. The Invector-Plus choke system provides superior shot pattern consistency compared to standard choke tubes.

Key Features

• Active Valve gas system cycles 2.75" and 3" shells automatically without adjustment
• Mossy Oak Bottomland camo pattern provides effective concealment in marshes and timber
• 28-inch barrel optimizes velocity for waterfowl loads and long-range shots
• Includes three Invector-Plus choke tubes (Full, Modified, Improved Cylinder)
• 4+1 capacity with drop-out trigger group for easy field cleaning
• Oversized bolt handle and safety operate reliably with hunting gloves
• Synthetic stock and forearm resist moisture and temperature changes

Field performance remains consistent across temperature extremes and various ammunition types. The 20-gauge platform reduces felt recoil compared to 12-gauge options while maintaining effective range for ducks and geese. The chrome-plated chamber and bore resist corrosion from steel shot and wet conditions. Hunters report reliable cycling with loads ranging from 7/8-ounce target shells to 1.25-ounce magnum waterfowl rounds.
