The Winchester SX4 Hybrid Hunter delivers fast-cycling semi-automatic performance with enhanced durability for waterfowl and upland hunting. This 20-gauge model combines Winchester's proven Active Valve gas system with a Flat Dark Earth Cerakote finish that resists corrosion in harsh field conditions.
What Makes This Different
The SX4's Active Valve gas system automatically adjusts to different shell lengths and loads, cycling everything from light 2¾" target loads to heavy 3" magnum waterfowl rounds without adjustment. The oversized bolt handle and enlarged loading port enable faster reloads compared to traditional semi-automatics. Quadra-Vent ports in the 28" barrel reduce felt recoil by up to 50% while maintaining consistent shot patterns.Key Features
