Patternmaster Code Black 20 Ga Duck Choke Tubes

This Code Black Duck tube will extend out the end of the barrel 1” and has an effective range up to 60 yards. Because of the patented stud ring inside of the tube, there is a much shorter shot string which will allow more shot on target all at once. This down range energy is sure to kill instead of cripple.

For best results we recommend ammunition velocities below 1550fps.
