The Winchester SX4 Hybrid Hunter is a 20 Gauge semi-automatic sporting shotgun built for field use and shotgun sports. It pairs a 28-inch back-bored, ventilated-rib barrel with a synthetic Realtree Timber stock finished in Flat Dark Earth Cerakote, aimed at hunters and serious shotgunners who need reliable function in varied conditions.
