Winchester® SX4 Waterfowl Hunter Semiautomatic Shotguns

Winchester® SX4® Waterfowl Hunter Semi-Auto Shotgun has improved ergonomics over the previous SX3 model, being slimmer and lighter, with a slightly forward balance point for fluid swinging and follow through. Larger, redesigned operating controls (safety, bolt handle, and bolt release) and a larger trigger guard facilitate getting on target quickly, as well as safe operation. This SX4 Waterfowl Hunter comes in full-coverage TrueTimber® DRT (Dead Right There) featuring a contrast of brown and gray, dark enough to blend into swamps and wetlands, with just enough yellow coloration for cattails and CRP fields. An Inflex Technology™ recoil pad utilizes directional deflection to pull the comb down and away from the shooter’s face, creating greater comfort and allowing for faster follow up shots. Winchester® SX4 Waterfowl Hunter Semiautomatic Shotguns uses Winchester’s Active Valve System™ that automatically self-adjusts, allocating the exact gas pressure necessary to fire a wide range of 2-3/4″–3-1/2″ hunting loads—critical for any semi-automatic shotgun used by avid waterfowl hunters who hunt multiple species in varied habitats. When firing heavy magnum loads gases vent upward and out of the Quadra-Vent™ ports in the forearm, further regulating bolt speed. The SX4 Waterfowl Hunter Semi-Auto Shotgun uses the proven Invector-Plus™ interchangeable choke tube system that works hand-in-hand with the back-bored barrel to reduce shot deformation and promote the uniform shot patterns you need to wallop birds at long range. A TRUGLO® fiber-optic front sight offers a precise sight picture in a variety of light conditions. A reversible crossbolt safety button is located on the rear of the trigger guard for quick access, and the trigger group easily drops out for field cleaning. Includes 3 chokes: F, M, IC.
