Patternmaster Code Black Duck 12 Gauge Long Range Choke Extended Ported for Browning Invector DS

Maximum Long-Range Waterfowl Performance with Proven Pattern Control

The Patternmaster Code Black Duck 12 Gauge Long Range Choke is purpose-built for serious waterfowl hunters who demand devastating pattern density, extended effective range, and reliable consistency. Designed specifically for Browning Invector DS shotguns, this extended, ported choke combines Patternmaster’s patented wad-stripping technology with porting to deliver tighter patterns, increased pellet energy, and reduced recoil for superior control in the blind.

Unlike traditional constriction-based chokes, the Code Black Duck controls the shot by slowing the wad while allowing the pellets to continue forward at higher velocity. This results in cleaner patterns, less pellet deformation, and increased knockdown power on ducks at longer distances.
