Winchester SX4 Waterfowl Hunter | 20ga | 28 in Barrel

The Winchester SX4 Waterfowl Hunter is a semi-automatic 20 gauge field shotgun finished in Mossy Oak Shadow Grass Habitat. It pairs a 28 inch ventilated-rib barrel with a synthetic camo stock and TRUGLO fiber-optic front sight for practical use in wet-field and migratory bird environments. The SX4 uses Winchester’s gas system and comes with Invector-Plus choke tubes and an Inflex Technology recoil pad to improve follow-up handling and shooter comfort.

Designed for waterfowl hunting and wet-field work, the SX4’s features also translate well to general field shooting where weather resistance and quick follow-up shots matter.
