12Ga Remington Pro Bore Code Black Goose
CODE BLACK GOOSE tubes will extend out the end of your barrel 1Â½â€ and have an effective range out to 70 yards. The difference between the Patternmaster CODE BLACK DUCK and Patternmaster CODE BLACK GOOSE is the length the tube sticks out the barrel. (DUCK = 1â€ vs. GOOSE = 1Â½â€) The added length is to accommodate a 3Â½â€ shell and still achieve a full pattern.
