The Patternmaster Code Black Duck 20 Gauge Long Range Duck Choke Extended Ported is engineered for waterfowl hunters who demand tight, uniform patterns and extended effective range from their 20 gauge shotgun. Designed for Browning Invector Plus and Winchester SX2, SX3, SX4, and SXP platforms, this choke delivers devastating performance on passing and late-season ducks where precision matters most.

Featuring Patternmaster’s proven wad-stripping technology and an extended, ported design, the Code Black Duck choke maximizes pellet energy, reduces flyers, and maintains dense patterns downrange for clean, ethical harvests.

Long-Range Duck Optimization

Purpose-built for longer shots, this choke delivers consistent, tight patterns that extend effective range without sacrificing uniform pellet distribution.

Patternmaster Wad-Stripping Technology

Innovative internal design separates the wad from the shot charge at the muzzle, resulting in shorter shot strings, increased pellet energy, and more consistent downrange patterns.

Extended Ported Design

The extended profile allows for easy, tool-free installation while porting helps reduce recoil and muzzle rise, enabling faster follow-up shots and improved shooting control.

Precision Fit for Browning and Winchester Platforms

Engineered specifically for Browning Invector Plus and Winchester SX2, SX3, SX4, and SXP shotguns to ensure secure fitment, proper alignment, and reliable performance.

Durable High-Performance Construction

Built from premium stainless steel and finished in Patternmaster’s rugged Code Black coating for corrosion resistance, durability, and long-term reliability in harsh waterfowl conditions.

Consistent Pellet Energy and Pattern Density

Maintains pellet speed and energy downrange, increasing lethality on tough, late-season birds at extended distances.
