Winchester SX4 Waterfowl Extreme Duck Boat Semi-Auto Shotgun 28"

The Winchester SX4 Waterfowl Extreme Duck Boat delivers rapid follow-up shots and weather-sealed reliability for serious waterfowl hunters. This semi-automatic shotgun combines Winchester's proven Active Valve gas system with specialized waterfowl features engineered for harsh marsh conditions.

What Makes This Different

The SX4's Active Valve gas system cycles 20% faster than traditional gas-operated shotguns, enabling quicker follow-up shots on fast-flying waterfowl. The Duck Boat configuration features a specialized camo pattern and corrosion-resistant finish that outperforms standard hunting shotguns in wet environments. Chrome-plated bore and chamber resist corrosion from moisture and salt spray that destroys unprotected firearms.

Key Features

• Active Valve gas system for 20% faster cycling than competitors
• 28-inch barrel optimized for waterfowl loads and extended range
• Invector-Plus choke system with three included choke tubes
• Synthetic stock with textured grip surfaces for secure handling
• Chrome-plated bore and chamber for corrosion resistance
• Drop-out trigger group for easy field cleaning
• Oversized bolt handle and safety for operation with gloves

Field performance centers on the SX4's ability to cycle everything from light 2¾-inch loads to heavy 3½-inch magnum shells without adjustment. The 28-inch barrel provides optimal velocity for steel shot while maintaining swing characteristics needed for crossing shots. Waterfowl hunters report reliable function in temperatures down to -20°F and after submersion in marsh water.
