Beretta OptimaChoke High Performance 20mm Extended 12Ga Choke Tubes with Alumimum Band

OPTIMA-CHOKE HP NEW LEGACY With the introduction of the SV-10 Perennia and Prevail Series Over&Under guns in 2008 a third Optima-Bore choke configuration was added, the Optima-Choke HP. As noted above under the Optima-Choke Plus section, the extended use of high performance steel and metal alloy non- shot imparts considerable stresses. In the case of the Optima-Choke Plus part of the solution was to use a choke tube design offering a thicker choke tube wall to better resist these forces. This in turn results in a heavier, larger diameter barrel.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.At today (2018), all new Beretta guns are made to use the Optima-Choke HP chokes, as they represent the most advanced technological solution to every need the shooter may face.

• STEEL CHOKE TUBES - Manufactured from high strength steel and finished in a nickel-alloy coating, these chokes guarantee significant corrosion resistance and have the ability to withstand the rigors of steel shot
• COMPATIBILITY - Optima-Choke HP 12 ga tubes are fully interchangeable on all Beretta barrels that are threaded for Optima-Choke HP (the Optima-Choke HP choke tubes are not interchangeable nor usable with barrels designed for the Optima-Choke system) Fits: Beretta A400 Xtreme, A400 Xplor, A400 Xcel, 690, 692, DT11, A300 Xtrema, SV10
• DURABLE CHOKE TUBES - 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 than found on the Optima-Choke system
• 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
• 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 (Optima-Choke, Optima-Choke Plus, Optima-Choke HP)
• WARNING: Use of the Optima HP choke tube in an Optima guns (without the HP designation) can cause severe damage to the choke tube and barrel when the gun is fired. Only use Optima HP choke tubes in these Optima HP guns: SV10 Perennia, SV10 Prevail, A400 Family, 690, 692, DT-11 and UGB25 Sporting.
