The Winchester SX4 Waterfowl Hunter is a semi-auto shotgun in 20 gauge with a 28″ back-bored vent rib barrel and 3″ chamber. Capacity is 4 rounds, and the square crossbolt safety is reversible. A TRUGLO fiber-optic front sight offers a precise sight picture in a variety of light conditions.
The SX4 uses Winchester’s Active Valve System that automatically self-adjusts, allocating the exact gas pressure necessary to fire a wide range of hunting loads. The SX4 Waterfowl Hunter 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 uniform shot patterns. Three flush-fit Invector-Plus choke tubes (improved cylinder, modified, full) come standard.
Larger, redesigned operating controls (safety, bolt handle, and bolt release) facilitate getting on target quickly, as well as safe operation. 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. The SX4 Waterfowl Hunter has improved ergonomics over the previous SX3 model, being slimmer and lighter, with a slightly forward balance point for fluid swinging and follow through.
