The Winchester Repeating Arms SX4 12 Gauge Semi Automatic Shotgun is the next iteration of the popular Super X3 line of auto loading shotguns. The Super X4 adds a ton of improvements like larger controls and a more ergonomic stock with non-slip texture for use in any environment. The black synthetic stock and all metal parts feature a no glare matte black finish to help prevent spooking game and the 28 inch barrel uses a vent rib design with a Tru-Glo front bead site for easy aiming in low light situations. The chrome plated bore and chamber combined with the Invector-plus choke system ensure a consistent and dense shot pattern giving you the confidence you need every time you pull the trigger. The Invector-Plus choke system is easy to change out and this shotgun comes with a full, modified, and improved cylinder bore allowing you to easily swap out depending on the type of load and hunting that you are doing. The Winchester SX4 12 Gauge shotgun also features a self-adjusting valve system that ensures reliable semi-automatic function with a wide variety of shot loads while the Quadra-vent ports expel excess gas to keep the system running cleaner for longer. When the time eventually comes to clean your shotgun, the trigger group is easily removeable allowing you to get to those hard to reach places. The SX4 also comes with spacers to adjust the length of pull and the Inflex recoil pad helps to direct recoil down away from your cheek to help reduce flinching. The Winchester SX4 semi automatic shotgun is the next hunting shotgun that you need.
