Patternmaster Retay 12 Gauge Code Black Decoy Choke Tube

Code Black Decoy - engineered to deliver consistent, reliable performance and even patterns with a shorter shot string.This choke offers an effective range of 15 to 40 yards. On paper you'll see a pattern similar to an Improved Cylinderlike choke, but due to the patented stud ring, the shot string is dramatically shorter. That means more pellets on target simultaneously for cleaner kills. Safe with lead, tungsten, bismuth, steel, nontoxic. Comes in Bronze finish and is nonported.
