Winchester's SX4 20-gauge delivers reliable performance with an Active Valve System that cycles various loads while reducing recoil. Features include a slimmer profile, improved ergonomics, Inflex Technology recoil pad, and fiber optic sights.
The SX4 represents a significant evolution in Winchester's semi-automatic shotgun design. This 20-gauge model combines proven reliability with thoughtful ergonomic improvements that benefit shooters of all experience levels.
Active Valve System The heart of the SX4 is its self-adjusting gas system. It intelligently allocates the precise gas pressure needed to reliably cycle a wide variety of loads—from light target rounds to heavy magnums. This means fewer malfunctions and more time shooting. Excess gases from heavy loads are channeled through Quadra-Vent ports for cleaner, more reliable operation.
Recoil Management The Inflex Technology recoil pad is engineered to direct and channel recoil impulses effectively. The pad's larger footprint spreads recoil over a wider area, while its geometry moves the comb down and away from your cheek. The result is noticeably reduced felt recoil—important for extended shooting sessions and younger or smaller-framed shooters.
Improved Handling Compared to its predecessor, the SX4 is slightly slimmer and lighter. The redesigned grip provides better comfort and control. Enlarged function controls and trigger guard make operation easier in cold weather or with gloved hands.
Whether you're hunting upland game, shooting clay targets, or simply enjoying time at the range, the SX4 delivers the reliability Winchester is known for. The 20-gauge is ideal for shooters seeking less recoil without sacrificing performance. The included choke tubes and adjustable length of pull make this shotgun adaptable to different shooting scenarios and body types.
