Patternmaster Code Black Duck Choke Tubes, 20ga

Description: Patternmaster Code Black Duck Choke Tubes, 20ga.  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 2-3/4" 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, 2-3/4" or 3" or 3-1/2" 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.

Note: Not for use with ammunition containing flight control wad or slug ammunition.  For best results, use ammunition velocities below 1550fps.
