Code Black Decoy Configuration

The Code Black Decoy is Patternmaster's field-oriented configuration for closer waterfowl applications. Compared with a dedicated Long Range choke, the Decoy configuration is intended to provide a more open pattern suited to birds working closer to the hunting setup.

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

Short Range Waterfowl Performance

The Short Range designation makes this choke particularly suited to waterfowl hunting situations where birds are expected to finish over decoys or present closer field opportunities.

Rather than relying on a single advertised distance, hunters should pattern their individual shotgun and ammunition combination to determine actual pattern density and distribution.

Browning Invector DS Compatibility

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

Browning has utilized several different interchangeable choke systems, including Standard Invector, Invector-Plus, and Invector DS. These systems should not be assumed interchangeable.

Always confirm that the exact shotgun uses Browning Invector DS before installing the choke.

Extended Choke Tube Design

The extended configuration projects beyond the muzzle when correctly installed. This provides additional external surface for handling and makes the choke easier to identify compared with a flush-mounted tube.

Non-Ported Construction

This Code Black Decoy features a non-ported design, providing a clean exterior profile without the machined ports found on some other Patternmaster Code Black configurations.

Built for Decoying Waterfowl

The combination of 20-gauge construction, Short Range/Decoy geometry, extended design, and Browning Invector DS compatibility creates a specialized choke option for hunters targeting ducks and geese over decoys and in other closer-range waterfowl situations.

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 patterns through the same choke.

Installation & Use

Before installing, removing, or inspecting the choke tube, ensure 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 installation instructions.

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.
