Winchester SX4 Compact | 12 Gauge | 24″ | 511230390

The Winchester SX4 Compact is a 12-gauge semi-automatic shotgun engineered for compact handling and reliable cycling. It pairs a 24″ back-bored vent-rib barrel with a 3″ chamber and the Invector-Plus choke system to deliver consistent shot patterns. The synthetic compact stock and shortened length of pull improve pointability for smaller-framed shooters and close-cover situations. This model is well suited to upland hunting and clay/sporting targets where quick swing and repeatable follow-up shots matter.
