Winchester SX4 Waterfowl Features The Winchester SX4 Waterfowl is built around the Active Valve gas operating system tested and refined through the SX2 and SX3 to become one of the most trusted autoloaders in the marsh. The 26 vent rib barrel carries a hardened chamber and bore along with the Mossy Oak Original Shadow Grass finish for concealment in wetland cover. A TruGlo fiber optic front sight gives a bright fast sight picture against low light and overcast skies common to early-morning hunts. The aluminum alloy receiver keeps overall weight at 6.12 lbs making the gun easier to carry and swing on crossing birds. Three Invector-Plus choke tubes in Full Modified and Improved Cylinder are included giving hunters the flexibility to pattern for decoying ducks or pass-shooting geese. The Mossy Oak Original Shadow Grass finish extends across the receiver barrel and composite stock for a consistent camouflage pattern in the blind. An Inflex Technology recoil pad reduces felt recoil from 20 Gauge loads over a long day of shooting while length of pull spacers let hunters fine-tune fit under heavy outerwear. The drop-out trigger group and large bolt handle speed up cleaning and operation in muddy wet conditions. The Winchester SX4 Waterfowl is a dependable field-ready autoloader for sale at GrabAGun.
