20ga CZ Active Choke Code Black Duck
Model Number: 5379
Patternmaster CODE BLACK DUCK tubes have 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” or 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. Our CODE BLACK DUCK tube can be used with steel or other non-toxic ammunition as well as lead, 2 ¾” or 3" shells. CODE BLACK DUCK tubes only come in a Non-Reflective Bronze titanium coating and are ported.
