Beretta Choke Tube Specifications
How can I identify which screw in choke tubes I should use in my Beretta shotgun, Mobilechoke, Optima-Choke, Optima-Choke Plus, or Optima-Choke HP?
Mobilchoke System Information:
Introduced in the mid 1980's the Mobilchoke tube system was first available for the model S687L over and under and later carried through virtually every model of fixed breech and semi-automatic shotgun. At this time the Mobilechoke is the only choke tube system adapted by Beretta to 12, 20, 28 gauge and .410. The Mobilchoke system continues to be the mainstay of the 680 series field grade over and under shotguns.
The conical parallel design of the Beretta choke tubes creates a more gradual taper inside the choke tube which gently transitions into a parallel section that runs to the muzzle end of the tube. The conical parallel design results in reduced shot deformation, improved pattern uniformity and increased pattern density.
The following pertains specifically to 12 gauge Mobilchoke tubes. While the dimensions noted will vary for the 20, 28 gauge and .410 tubes, identification is very much self evident.
Barrels that use the Mobilchoke will typically be marked only with the gauge marking.
Mobilchoke choke tubes will be marked PB or ST and the degree of choke. If the choke tube is steel shot compatible it will also be marked SP.
The start of the threaded portion of the 12 gauge Mobilchoke tube is located a nominal 41.5 mm (1.63 inch) from the breech end of the choke tube.
The length of the threaded portion is a nominal 9.15 mm (.360 inch).
The major diameter of the choke tube thread is 20.62 mm (.811 inch).
In the year 2000 Beretta introduced the 12-gauge Optima Bore barrel design into some of our competition shotguns. This new barrel utilized a larger internal bore dimension known to some as âback-boringâ and required a new choke tube design to give the proper constrictions. The Optima barrels can be identified by locating the letters âOBâ stamped next to the barrel gauge stamp. Barrels marked with the "OB" stamp will use the Optima-Choke system. This design features a longer internal transition taper into the choke constriction, making the overall length of this tube longer than the original Mobilchoke tube.
Barrels that use the Optima-Choke will typically be marked OB immediately adjacent to the gauge marking.
Optima-Choke choke tubes will be marked Optima-Choke.
The start of the threaded portion of the Optima-Choke tube is located a nominal 50.78 mm (2.00 inch) from the breech end of the choke tube.
The length of the threaded portion is a nominal 15.9 mm (.625 inch).
The major diameter of the choke tube thread is 20 mm (.787 inch).
At this time the Optima-Bore/Optima-Choke system is typically used on competition 391 series semi-automatic and 680 series over and under shotguns and Teknys Gold series only in the 391 Urika2 field guns.
Important Note: The Optima-Choke choke tubes are not interchangeable nor usable with barrels designed for the Optima-Choke HP system. Use of Optima-Choke choke tubes in barrels designed for use with Optima-Choke HP tubes may result in catastrophic damage to your barrel and personal injury or death to the shooter or persons in the immediate vicinity!
Optima-Choke Plus Information:
With the introduction of the model 391 Xtrema shotguns in 2003 the Optima barrel configuration was added into the 391 12-gauge line of field shotguns. In order to handle a higher volume of steel shot shells used in field hunting, the Optima-Choke tube was revised and manufactured with a thicker wall size. This revised choke tube was named the Optima-Choke Plus and featured the same Optima-Choke internal dimensions and performance but has a larger outside diameter and revised thread location.
Barrels that use the Optima-Choke Plus will typically be marked 12 gauge 3 1/2" with no other identifying code mark in the immediate area of the gauge marking.
Optima-Choke Plus choke tubes will be marked Optima-Choke-Plus.
The start of the threaded portion of the Optima-Choke Plus tube is located a nominal 41.9mm (1.64 inch) from the breech end of the choke tube.
The length of the threaded portion is a nominal 10 mm (.394 inch).
The major diameter of the choke tube thread is 20.58 mm (.810 inch).
At this time the Optima-Choke Plus system is typically used on the Xtrema, Xtrema2 semi-automatic field guns and 471 Silver Hawk side by side shotguns (12 Ga.).
Important Note: The Optima-Choke Plus choke tubes are not interchangeable nor usable with barrels designed for use with any other Optima-Choke/Optima-Choke HP system. Use of Optima-Choke Plus choke tubes in barrels designed for use with any other Optima-Choke/Optima-Choke HP tubes may result in catastrophic damage to your barrel and personal injury or death to the shooter or persons in the immediate vicinity!
Optima-Choke High Performance (Optima-Choke HP) information:
With the introduction of the SV-10 Perenina and Prevail series over and under shotguns 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-toxic 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. 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 than 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.
Barrels that use the Optima-Choke HP will be marked OB HP immediately adjacent to the gauge marking.
Optima-Choke HP choke tubes will be marked Optima-Choke-HP.
The start of the threaded portion of the Optima-Choke-HP tube is located a nominal 40 mm (1.57 inch) from the breech end of the choke tube.
The length of the threaded portion is a nominal 19 mm (.748 inch).
The major diameter of the choke tube thread is 20 mm (.787 inch).
At this time the Optima-Choke HP system is typically used on the SV-10 Perennia and Prevail series over and under and the UGB 25 Gold Sporting semi-automatic shotgun.
Important Note: The Optima-Choke HP choke tubes are not interchangeable nor usable with barrels designed for the Optima-Choke system. Use of Optima-Choke HP choke tubes in barrels designed for use with Optima-Choke Tubes may result in catastrophic damage to your barrel and personal injury or death to the shooter or persons in the immediate vicinity!
Each of the above choke tube types is designed for use with a specific type barrel and as such features different thread locations and external measurements, none can be interchanged with the other Beretta choke types. 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)
Within each of the three choke types we offer different variations of length and finish. The length variations available for each type is flush fit or extended choke tubes. Most field shotguns are equipped with flush chokes. Sporting and skeet shotguns will be equipped with extended tubes. The Beretta factory may supply trap guns with either choke variation as determined. Within the extended choke variations we offer two finishes. Since the extended chokes are exposed past the shotgun muzzle we offer choke tubes with a black non-reflective finish for hunters. A bright finish tube with colored bands is offered for competitive shooters, this band allows easy identification of the tube constriction.
It should be mentioned that two other choke types saw a limited use. Supplied with some 302 and 303 models shotguns was an early version of the Mobilchoke where the tube body was not threaded but smooth. This type tube was dropped into the muzzle end of the barrel and secured by collar threaded onto the barrel muzzle. This tube type is no longer available from Beretta. The second type was offered on an early version of the DT-10 shotgun made specifically for trap, this shotgun was known as the Vandalia model. These tubes are similar in size to the Optima choke flush tube but are not interchangeable with them. We still carry replacement tubes for this specific model.
