12 Gauge Code Black Duck Choke Tube - 17-4 Stainless Steel

In this review the 12 Gauge Code Black Duck choke tube is presented for hunters who need one versatile choke that can cover waterfowl, dove fields and turkey setups without changing tubes often. The bottom line: this tube is for shooters who value consistent, condensed patterns and durable construction; its patented stud ring design shortens the shot string so hits come with more of the load, and the Titanium Nitride coated 17-4 stainless construction promises long service. For those who want long-range performance from a single choke, this review finds the Code Black Duck delivers.

Key Features

• Versatile performance: One tube covers close timber work, mid-range goose shots and dove fields so you can carry fewer choke options in the blind.
• Stud ring design: The patented ring shortens the shot string so pellets arrive tighter together for cleaner, more effective hits.
• Pattern options: Produces patterns similar to a Full with 2 3/4'-3' shells and Improved Modified with 3 1/2' shells for adaptable spread control.
• Long effective range: Experienced users report consistent hits out to distances many consider lucky, with effective performance quoted up to 60 yards depending on load.
• Durable construction: Made from heat treated 17-4 aircraft quality stainless steel with Titanium Nitride coating to resist wear and maintain fit.

Who It's For

The Code Black Duck is best for mixed-bag waterfowl and upland hunters who need a single choke that handles a wide variety of loads and scenarios, from tight timber shots to mid-range decoy spreads. It also suits owners of Benelli and similar shotguns who want a choke that fits well and keeps a consistent pattern across commonly used shell lengths.

Hunters who exclusively use slugs, specialized turkey loads, or require an extreme open or full-only pattern should look elsewhere, since this tube is not intended for slug use and is optimized to produce a balance between tight and moderate patterns rather than an extreme single-purpose spread.

Pros & Cons

Pros

• Tighter, more condensed patterns thanks to the stud ring, improving hit probability on decoys.
• Wide usefulness across loads and species reduces the need to carry multiple chokes in the field.
• Solid build quality and finish; customers note good fit and attractive appearance in their guns.
• Reported effective range out to long distances for experienced hands, adding versatility.

Cons

• Not suitable for slug ammunition, so it does not replace a dedicated slug tube for single-projectile shooting.
• Performance can vary with pellet size and load velocity, and best results require staying below recommended velocities.
