Product Description

What's in the Box

  • Wincheseter SX4 20 Gauge Shotgun
  • (3) Choke Tubes: Full Modified Improved Cylinder
  • Choke Tube Wrench
  • Cable Lock 
  • Owner's Manual

The next level of performance. This Super X4 follows on the heels of the most successful Winchester autoloader ever: the Super X3 Black Shadow. There would be no point to the new SX4 if it did not take function, handling and egonomics to the next level. And it does. This is a dedicated hunting machine with it's all-black exterior that is definitely non-glare to prevent spooking game. Critical functional controls are larger and easier to operate - a real benefit in damp weather and cold conditions.

Firearm Features

  • Synthetic Stock with Improved Ergonomics, A Smaller Pistol Grip and Textured Gripping Surfaces give your hands a sure, non-slip grip. The non-glare matte black finish won’t spook wary game
  • Back-Bored Technology provides optimum shot patterns that are dense and even
  • Invector-Plus Choke Tube System offers consistent patterns to match your target situation
  • Hard Chrome-Plated Chamber and Bore make these surfaces highly resistant to wear and corrosion
  • Truglo Long Bead Fiber-Optic Front Sight offers a true, precise sight picture
  • Vent Rib gives you a smooth, clean sighting plane
  • Self-Adjusting Active Valve System cycles a wide variety of loads while reducing “felt recoil”
  • Quadra-Vent Ports vent excess gases for cleaner operation
  • Drop-Out Trigger Group allows for easy cleaning
  • Ambidextrous Crossbolt Safety is easily reversible
  • Larger Bolt Handle and Bolt Release Button are faster and easier to operate
  • Length of Pull Spacers allow stock adjustments to achieve a perfect fit
  • Inflex Technology Recoil Pad directs “felt recoil” down and away from your cheek to reduce flinch and fatigue
