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

The Winchester SX4 Waterfowl Hunter delivers reliable semi-automatic performance for serious waterfowl hunters who demand consistent cycling in harsh marsh conditions. This 20-gauge platform combines Winchester's proven Active Valve gas system with specialized waterfowl features that maintain function when other shotguns fail.

What Makes This Different

The Active Valve gas system automatically adjusts to different shell lengths and loads without manual intervention, ensuring reliable cycling from light 2¾" loads to heavy 3" magnums. Unlike fixed gas systems that require adjustment or cleaning between different ammunition types, this adaptive technology maintains consistent performance across the full range of waterfowl loads. The oversized bolt handle and controls function smoothly even with heavy gloves in freezing conditions.

Key Features

• Active Valve gas system cycles 2¾" through 3" shells automatically
• 28" barrel with 3 Invector-Plus choke tubes (Full, Modified, Improved Cylinder)
• 4+1 capacity with drop-out trigger group for easy cleaning
• Realtree Timber camouflage covers all exterior surfaces
• Oversized bolt handle and safety designed for gloved operation
• Chrome-plated bore and chamber resist corrosion from wet conditions
• Textured grip surfaces maintain control in wet weather

Field testing demonstrates consistent cycling across ammunition weights from 7/8 oz. target loads to 1¼ oz. waterfowl loads without adjustment. The 28" barrel length provides optimal velocity for steel shot while maintaining manageable swing characteristics in blinds and boats. Hunters report reliable function in temperatures down to -20°F and after submersion in marsh water.
