Beretta Choke Tubes Guide

There are several chokes available for Beretta shotguns, how can you identify the right one? In fact, it is not that hard as each shotgun only accept one “Family” of chokes in only one Gauge, within those you can choose any model that you like the most (model examples: flush, extended, ported, black edition, etc.)

For better explain, here the main variants of the fundamental data you need:

  • “Family”: Mobile-Choke, Optima-Choke, Optima-Choke Plus, Optima-Choke HP (latest model developed)
  • Gauge: 12, 20, 28, .410

In the following paragraphs, you will discover the best methods to identify the “Family” of chokes compatible with your shotgun (Gauge is considered known by the owner). Those apply independently if they are Overe&Under, Semiauto or SideBySide

 

1. VISUAL METHOD

The fastest way to identify the “Family” is to take down one choke you are currently using on your shotgun, clean it and cheek the markings on the side of the choke, here an example:

In the example image, you see an Optima-Choke HP Choke

Note: Mobile-Choke “Family” could also be marked as “PB” or “ST”

 

Found? Select yours:   Mobil-Choke    Optima-Choke    Optima-Choke Plus    Optima-Choke HP

Not Found? Check next method!

 

 

2. BARREL MARKINGS METHOD

For this method, you will only need your shotgun and check the markings near the Gauge mark:

Found? Select yours:   Mobil-Choke    Optima-Choke    Optima-Choke Plus    Optima-Choke HP

Not Found? Check next method!

 

 

3. SERIAL NUMBER METHOD

If nothing else works, we can obtain the right choke “Family” from the serial numbers present on your shotgun. In order to do so, you need to send us an email with both:

  • Shotgun serial number
  • Barrels serial number

 

We will reply as soon as possible, typically a couple of working days. To send an email, use the form at the following link and insert all the info required (in addition to the 2 serial numbers):

1980s: IT ALL STARTED WITH THE MOBIL-CHOKE 

Introduced in the mid 1980's the Mobil-Choke tube system was first available for the model S687L Over&Under and later carried through virtually every model of fixed breech and semi-automatic shotgun. At this time, the Mobile-Choke was the only choke tube system adapted by Beretta to 12, 20, 28 and .410 gauge. The Mobil-Choke system continues to be the mainstay of the 680 series field grade Over&Under shotguns.

The iconic parallel design of the Beretta choke tubes creates a more gradual taper inside which gently transitions into a parallel section that runs to the muzzle end of the tube. The parallel design results in reduced shot deformation, improved pattern uniformity and increased pattern density.  
 

2000: EVOLUTION BRINGS TO THE OPTIMA-CHOKE

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 “back-boring” and required a new choke tube design to give the proper constrictions.

The Optima barrels can be identified by locating the letters “OB” stamped next to the barrel gauge stamp. Barrels marked with the "OB" stamp will use the Optima-Choke “Family”. This design features a longer internal transition taper into the choke constriction, making the overall length of this tube longer than the original Mobil-Choke tube.
 

2003: EXTREME USE CREATES OPTIMA-CHOKE PLUS 

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.
 

2008: OPTIMA-CHOKE HP NEW LEGACY 

With the introduction of the SV-10 Perennia and Prevail Series Over&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. 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.

At today (2018), all new Beretta shotguns are made to use the Optima-Choke HP chokes, as they represent the most advanced technological solution to every need the shooter may face.
