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. Crafted from American made, titanium infused 17-4 aircraft-quality stainless-steel and are heat treated to the optimum level for best performance. Note: Testing done by Ballistics Performance has determined that ammunition with a velocity of 1550fps and below will achieve the best results with Patternmaster Tubes. Not for use with ammunition containing flight control wad. Patternmaster's 12ga Benelli/Beretta Mobile tubes will interchange with Benelli, Sport (After 2006), Nova, Super Nova, and Super Black Eagle; Beretta A300, Silver Pigeon, White Onyx, Ultralight, and Diamond Pigeon. There are other guns that interchange as well like Stoeger 2000, P-350 Pump, and the Franchi current production guns, Legacy Escort, Huglu, CZ USA, Hatson, some Charles Daly Models, Savage, Smith and Wesson current production, and Tri-Star Phantom Field and Silver Series

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.
