20ga Benelli Advanced Impact Code Black Duck Choke Tube is a Patternmaster Code Black choke tube for 20ga Benelli Advanced Impact shotguns. It is built for open-water and mixed waterfowl hunts and tuned to deliver a longer-range waterfowl pattern with Patternmaster's shorter shot string.

The Code Black design helps shorten the shot string so more pellets arrive on target together. On paper, this tube patterns full-like with an effective range of 40-60 yards. Compatible with lead, steel, tungsten, bismuth, and other non-toxic shot when used according to firearm and ammunition manufacturer guidance.
