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.
