Product Description

What's in the Box

  • Winchester SXP Shadow Marine Defender 12 Gauge Pump Shotgun with Matte Chrome Finish
  • Cable Lock
  • Owner's Manual

Ready for the wet and wild. The Shadow Marine Defender is the most advanced version of the popular Marine Defender line. Originally conceived for protection for coast bear hunters and seafaring boaters, Everything is designed to protect against the elements while protecting you. The hard chromed plating on major exterior surface and the hard chrome-plated bore make it able to stand up to wet conditions and offer extra protection in salty environments.

Versatile under real use in the field. Yes, this SXP has a specific design purpose, but it also is ready to provide meals around camp with the use of its Invector-Plus interchangeable choke system.

Firearm Features

  • MATTE HARD CHROME PLATING on the barrel, magazine tube and slide arms for added resistance to wear and the elements
  • SYNTHETIC PISTOL GRIP STOCK WITH TEXTURED GRIPPING SURFACES give your hands a sure, non-slip grip and the non-glare matte black finish won’t give you away
  • TWO INTERCHANGEABLE COMB PIECES allow you to fine-tune drop at comb for use with iron, electronic or optical sights
  • TWO INTERCHANGEABLE LENGTH OF PULL SPACERS allow you to fine-tune length of pull for a perfect stock fit
  • TACTICAL RIBBED FOREARM for better control when you need it most
  • HARD CHROME-PLATED CHAMBER AND BORE make these surfaces highly resistant to wear and corrosion
  • INVECTOR-PLUS CYLINDER CHOKE TUBE handles both slugs and buckshot
  • 3" CHAMBER gives you the ability to reach out for challenging shots
  • BLACK CHROME PROTECTION on the bolt and other components lasts longer than traditional bluing
  • TRADITIONAL BRASS BEAD FRONT SIGHT plus a removable TRUGLO® fiber-optic sight offer a fast, natural sight picture
  • ALLOY RECEIVER is drilled and tapped for scope bases
  • ROTARY BOLT with four massive lugs provides strength, support and solid lockup
  • CROSSBOLT SAFETY is easily operated, even with gloves
  • INFLEX TECHNOLOGY RECOIL PAD directs “felt recoil” down and away from your cheek
