Product Description


Patternmaster created the Code Black line of tubes for the world's most serious hunters. The Code Black line of tubes incorporates the same wad control technology that helped revolutionize the shotshell market. With well over 60 combined years of research and development to aid in its design, Patternmaster is certain you'll create a mass casualty event with Code Black.

Code Black Duck tubes will extend out the end of your barrel 1" and have an effective range out to 60 yards. You will see patterns similar to a full constriction choke on paper, but because of the patented "stud ring" inside the tube, there is a much shorter shot string. This shorter shot string will allow more shot on target all at once, so your down range energy is sure to kill instead of cripple.


  • Made of aircraft quality 17-4 stainless steel
  • Stud ring holds the wad cup for a fraction of a second to create the tightest and densest patterns
  • SecureFit threading provides tight fitting with zero pressure loss
  • Heat treated for maximum durability and coated in a titanium non-reflective bronze finish
  • Reduces recoil and muzzle jump
