Winchester SX4 Features The Active Valve gas system inside the SX4 has been tested and refined across three generations of Winchester Super X shotguns self-regulating gas pressure across a range of shell loads so the action cycles reliably whether the hunter is running light target loads for practice or heavy magnum waterfowl loads in the field. A drop-out trigger group simplifies field cleaning after a muddy morning in the marsh letting the hunter pull the entire trigger assembly for a thorough clean without needing to disassemble the whole receiver. Sling swivel studs are built into the stock for hunters who want to carry the shotgun hands-free between blinds or while wading through flooded timber. The included Invector-Plus choke tubes full improved modified and modified cover the range of waterfowl shot distances a hunter is likely to face in a single outing. The Realtree Legacy camo finish extends across both the barrel and the synthetic stock for a cohesive concealment pattern rather than a mismatched two-tone look helping the shotgun disappear in typical waterfowl cover. A generous trigger guard opening keeps the shotgun usable with heavy gloves on cold mornings in the blind an easily overlooked detail that matters when the temperature drops before shooting light. The vent rib barrel helps dissipate heat during repeated shots while also reducing barrel mirage that can distract from tracking a bird in flight. With a length of pull of 14.25 inches and weighing 6.75 lbs the SX4 balances well for repeated mounting and swinging on incoming birds. This dependable waterfowl autoloader is available for sale at GrabAGun for hunters who want a proven gas system in a purpose-built camo finish.
