Extends 1-1/2" from the end of your barrel
Helps you achieve a full pattern
Stud ring creates a shorter shot string
Increases downrange energy
Non-reflective bronze titanium coating
Patternmaster's Code Black Goose Choke Tube will extend out the end of your barrel 1-1/2" and has an effective range out to 70 yards. The added length is to accommodate a 3-1/2" shell and still achieve a full pattern. You will see patterns similar to a full constriction choke on paper with a 2-3/4", 3", and 3-1/2" 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 shots on target all at once so your downrange energy is sure to kill instead of cripple. Code Black Goose Tubes come in a non-reflective bronze titanium coating. 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.
Patternmast'ers 12-ga. Remington Pro Bore is interchangeable with all Parker models and new models of the 1100 Competition.
