Code Black Duck Long Range Configuration

The Patternmaster Code Black Duck Long Range is designed around the demands of waterfowl hunting. Its specialized choke geometry provides a dedicated longer-range configuration for hunters using compatible 20-gauge shotguns.

Actual pattern characteristics depend on the individual shotgun, ammunition, pellet size, shot material, payload weight, and specific load being used.

Browning Invector DS Compatibility

This Code Black Duck choke is specifically designed for compatible Browning Invector DS choke systems.

Browning has used several choke systems across its shotgun lineup, including Standard Invector, Invector-Plus, and Invector DS. These systems should not be assumed to be interchangeable.

Always verify that the exact shotgun utilizes the Browning Invector DS system before installing this choke tube.

Extended Choke Tube Design

The extended configuration projects beyond the muzzle when correctly installed. The additional external surface makes the choke easier to identify and provides a convenient gripping area during installation and removal.

Ported Construction

This Code Black Duck model features a distinctive ported design incorporated into the extended section of the choke tube. The machined ports are a defining feature of this configuration and distinguish it from non-ported waterfowl choke designs.

Built for Waterfowl Hunting

The combination of 20-gauge construction, Code Black Duck geometry, Long Range designation, extended profile, ported construction, and Browning Invector DS compatibility creates a specialized choke option for demanding waterfowl applications.

Long Range Performance

Patternmaster's Long Range designation is intended for hunters looking for tighter pattern performance at longer field distances compared with more open choke configurations.

Because every shotgun and ammunition combination can perform differently, actual pattern density and effective performance should be verified through pattern testing.

Pattern Testing

Pattern testing is recommended whenever changing choke tubes or ammunition. Test the shotgun using the exact ammunition intended for hunting to determine actual pattern density, distribution, and point of impact.

Different pellet materials, shot sizes, payload weights, and ammunition designs can produce substantially different results through the same choke.

Installation & Use

Before installing, removing, or inspecting the choke tube, verify that the shotgun is completely unloaded.

Confirm that the firearm uses the Browning Invector DS choke system and follow both Patternmaster's and the firearm manufacturer's instructions for installation and removal.

Use only ammunition and shot materials specifically approved for the firearm and choke tube.

Care & Maintenance

Periodically remove and inspect the choke tube according to manufacturer recommendations. Keep the choke and barrel threads clean and apply an appropriate choke-tube lubricant or anti-seize compound when recommended.

Do not use a choke tube exhibiting damaged threads, cracks, deformation, corrosion, or excessive wear.
