Winchester SX4 12 Gauge Semi-Auto Shotgun 28" Barrel 4+1 Capacity

The Winchester SX4 semi-automatic shotgun delivers rapid cycling performance with a 28-inch barrel engineered for versatility across hunting and sporting applications. This 12-gauge platform combines Winchester's proven gas-operated system with modern manufacturing precision to handle everything from light target loads to heavy 3-inch magnum shells.

What Makes This Different

The SX4's Active Valve gas system automatically adjusts to different shell lengths and loads without manual intervention, cycling reliably from 2¾-inch light loads through 3-inch magnums. The chrome-plated chamber and bore resist corrosion while maintaining consistent performance across thousands of rounds. Winchester's Invector-Plus choke system provides superior pattern control compared to standard threaded chokes, with three factory chokes included for immediate field readiness.

Key Features

• Active Valve gas system cycles 2¾" to 3" shells automatically
• 28-inch barrel with chrome-plated bore and chamber for corrosion resistance
• 4+1 capacity with drop-out trigger group for easy maintenance
• Three Invector-Plus chokes included (Full, Modified, Improved Cylinder)

Field testing demonstrates consistent cycling across various ammunition weights, from 1-ounce target loads to 1⅝-ounce waterfowl rounds. The 28-inch barrel length provides optimal velocity for hunting applications while maintaining manageable swing characteristics for upland birds and clay targets. Weather-sealed action components function reliably in wet conditions, making this shotgun suitable for waterfowl hunting and adverse weather shooting sports.
