Patternmaster CODE BLACK DUCK tubes will extend out the end of your barrel 1 inch and has an effective range of 50 to 70 yards. You will see a patterns similar to a Full constriction choke on paper with a 2 ¾" - 3" shell, 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. The CODE BLACK DUCK tube can be used with steel or other non-toxic ammunition as well as lead,2 ¾" - 3" or 3 ½”; shells. Pick your favorite shot size to use which can range from 8 to BB Non-Toxic/Steel and Lead 8 to 00 Buck. CODE BLACK DUCK tubes only come in a Non-Reflective Bronze titanium coating and are ported. Patternmaster tubes are made of Carpenter Custom 630 (aircraft quality) 17-4ph stainless steel and are heat treated to the optimum level for best performance.

Crafted from American made, titanium infused 17-4 aircraft quality stainless-steel and are heat treated to the optimum level for best performance. If you’re like most of us and are looking for simple but effective the Code Black Duck is the tube for you. Expect a tighter pattern similar to a “Full” when shooting 2 ¾”-3” shells and “Improved Modified” with 3 ½” shells. Effective distances vary from load and pellet size...but experienced hands should expect clean kills at distances most would consider lucky. The Code Black Duck’s versatility is not only in its patented design, but in its construction. Our patented stud ring design shortens the shot string immensely...so when you hit your quarry, you hit ‘em with the entire load at once. Imagine a single tube that will get it done in everything from the Arkansas timber, Eastern Shore Geese, all the way Georgia Dove Field and still hold its own on a Missouri Longbeard. The Code Black Duck is arguably the world’s most versatile tube.
