Patternmaster's Code Black choke uses special wad-control technology.

Patternmaster’s Code Black choke tubes incorporate the company’s special wad-control technology to deliver maximum payloads and energy.

The Code Black has five studs cut out of the walls of the tube, which creates a tight 2- to 3-foot shot string — compared to 15 to 20 feet from conventional tubes — that delivers maximum lethality. Where the studs are placed dictates the pattern created.
