Winchester's legendary SX4 autoloader built for waterfowl hunting with proven Active Valve gas system, 3.5" chamber, Realtree Legacy camo, and three Invector choke tubes.
The Winchester SX4 represents the pinnacle of waterfowl shotgun engineering. Built from the ground up for harsh marsh conditions, this semi-automatic 12-gauge combines reliability with practical performance.
Active Valve Gas System The heart of the SX4 is Winchester's proven Active Valve operating system. Refined through generations of the SX3 and SX2, this gas-operated mechanism has been tested and perfected in real-world conditions. The result is an autoloader you can depend on when it matters most.
Specifications
Your SX4 comes equipped with three Invector choke tubes—full, modified, and improved cylinder—allowing you to match your shot pattern to any waterfowl situation. Sling swivel studs are factory-installed for secure carry.
Waterfowl hunting demands a shotgun that cycles reliably in cold, muddy conditions. The SX4's gas system handles everything from light target loads to heavy magnum shells without complaint. The Realtree Legacy camouflage pattern blends seamlessly in marsh environments, while the synthetic furniture resists corrosion and moisture damage.
This is a shotgun built by hunters, for hunters.
