Specification Brand : Beretta BulletPoint1 : OPTIMACHOKE HP CHOKE 12 GA - 2cm ex. Optimachoke HP choke tube (2cm exits the barrel when installed) with special DLC coating that guarantees better performance due to the friction reduction function and increasing resistance to climatic conditions BulletPoint2 : DIAMOND LIKE CARBON COATING (DLC) - It is a hydrocarbon coating that is generated through plasma deposition technique (reduction in the friction coefficient, greater wear resistance and an increase in hardness due to the rigidity of the created film) BulletPoint3 : INCREASED WALL THICKNESS - Increased wall thickness at the muzzle end of the choke tube where the greatest degree of choke constriction typically occurs and stresses are the highest without having to use the larger barrel contour BulletPoint4 : COMPATIBILITY - These steel choke tubes are compatible with DT11; 694; 1301 COMP PRO; A400XCEL A400 UPLAND; A400 XTREME PLUS; 686 Silver Pigeon I; all 12 Ga guns use OCHP (Optimachoke HP) chokes BulletPoint5 : ENGRAVED DETAILS - Every Beretta choke tube has information engraved on the tube to identify the manufacturer (PB), the constriction (F, IM, M, IC, CYL), the approval for steel shot use (SP) and the choke type Color : Silver Department : unisex-adult ExternallyAssignedProductIdentifier1 : 082442943367 ExternallyAssignedProductIdentifier2 : 0082442943367 ExternallyAssignedProductIdentifier3 : 00723189114923 ImportDesignation : Made in USA or Imported IncludedComponents : Choke Tube ItemDisplayDimensions_Height : 7 inches ItemDisplayDimensions_Length : 5 inches ItemDisplayDimensions_Width : 1 inches ItemDisplayWeight : 0.15 pounds ItemName : Beretta Optimachoke High Performance Extended 20mm 12Ga DLC Coating Stainless Steel Choke Tube, Light Modified (E6D075) ItemPackageDimensions_Height : 14.5 centimeters ItemPackageDimensions_Length : 2.6 centimeters ItemPackageDimensions_Width : 11.5 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : gun-stock-accessories Manufacturer : Beretta Material : Aluminum ModelName : 1130297 ModelNumber : 1130297 NumberOfBoxes : 1 NumberOfItems : 1 PackageLevel : unit PartNumber : E6D075 Pattern : Solid ProductDescription : BERETTA CHOKE TUBE OPTIMACHOKE HP "DLC MODEL" 20MM EXT 12 GA
2cm extended Optimachoke HP choke tube (2cm exits the barrel when installed) with special DLC coating that guarantees better performance thanks to the friction reduction function, as well as increasing resistance to climatic conditions. They are supplied with the protective case, and the second generation packaging which includes the most relevant information on the front.

OPTIMA-CHOKE HP SYSTEM
One of the principal objectives in designing the Optima-Choke HP (OB HP)system was to develop a choke tube system that would withstand the rigors of the extended use of heavy payloads of steel/metal alloy shot while being able to retain the weight saving and handling characteristics of the lighter Optima-Choke barrel contour. To accomplish this Beretta engineers designed a choke system locating the threaded portion of tube a nominal 10 mm (.394 inch) further to the rear of the muzzle end of the tube then found on the Optima-Choke system. This effectively created an increase in wall thickness at the muzzle end of the choke tube where the greatest degree of choke constriction typically occurs and stresses are the highest without having to use the larger barrel contour.
