Typical listed compatible shotguns include:
Always verify the barrel is marked for Optima/OptimaChoke before use, as this tube is not intended for Mobilchoke or Optima HP systems.
Material, Construction, and Finish
The JCOCN16 choke tube is built for long-term durability and consistent pattern performance:
Beretta OEM chokes are machined with high concentricity and a smooth internal finish to align with their barrel tolerances and maintain consistent patterning. Cheaper Than Dirt+1
Elongated Cone Design and Pattern Performance
A key technical feature of the OptimaChoke series is the longer, slimmer body and elongated internal taper compared to older Mobilchoke tubes:
This design is beneficial whether using lead or many modern non-toxic loads (within Beretta’s published restrictions for choke and shot combinations).
Constriction and Intended Range
The JCOCN16 is specified as an Improved Cylinder constriction:
In general pattern terms (actual results vary by load and barrel):
Improved Cylinder is typically used for short to medium range work where a more open pattern is desired—commonly out to ~25–35 yards depending on load and target size.
It is often recommended for upland birds over pointing dogs, close-range waterfowl over decoys with appropriate non-toxic shot, and general-purpose clay shooting when wider patterns are advantageous.
Retailers frequently position this specific choke as suitable for waterfowl and range shooting on Optima-equipped Beretta shotguns. Blackstone Shooting Sports+2Hinterland Outfitters+2
Dimensions, Style, and Identification
While exact overall length can vary slightly by specific model run, common specification highlights include:
The flush design keeps the muzzle profile smooth, which can be advantageous in dense cover and for users who prefer a traditional appearance without extended tubes.
Use, Compatibility, and System Notes
Key use and compatibility considerations:
For Optima Bore barrels only: The tube is designed for 12-gauge Optima Bore barrels with the OptimaChoke system and is not compatible with:
Interchangeability: OptimaChoke tubes of different constrictions are fully interchangeable across 12 GA Optima barrels as needed for specific disciplines or species. Ready Gunner+3Black Market Arms+3AmmoJo+3
Typical application examples:
Hunting: Upland game, early-season waterfowl over decoys (with suitable loads and within specified choke/steel shot guidelines). Blackstone Shooting Sports+2Hinterland Outfitters+2
Sporting / clays: Stations requiring more open patterns, or as a general-purpose choke for skeet-style and close-range targets.
Always refer to Beretta’s official guidance to confirm shot size and material compatibility (e.g., restrictions on large steel shot) for Improved Cylinder Optima tubes.
