1. Beretta Mobilchoke

The Beretta Mobilchoke system has set the standard for interchangeable chokes since its introduction in the 1980s. Originally developed for the S687L model, this thread system can now be found in almost all Beretta models with fixed breeches and semi-automatic shotguns. Here you will learn how the system performs in practice – from compatibility to performance in various shooting situations.

Compatibility with Models and Calibers

The Mobilchoke system was developed for a variety of calibers, including 12, 20, 28 gauge, and .410. It is a central component of the 680 series and is primarily used in hunting over-and-under shotguns. Compatible models include the Beretta Silver Pigeon I (hunting models), A300 Outlander, 687 (hunting models), and some 391 models. The barrels that use the Mobilchoke system are usually only marked with the corresponding caliber marking, making identification easier.

Easy Handling and Maintenance

The Mobilchoke tubes are clearly marked – with PB/ST and for steel shot additionally with SP. In 12-gauge models, the tubes start 41.5 mm from the rear end of the barrel, have a thread length of about 9.15 mm, and a diameter of 20.62 mm. These precise markings make changing and selecting the tubes straightforward and user-friendly.

Adaptability to Different Shooting Scenarios

The Mobilchoke system is designed to flexibly adapt to different shooting conditions. It allows for the individual tuning of the weapon to the respective environment. For example, full chokes concentrate about 70% of the shot load in a 76 cm circle at a distance of around 37 meters. Half chokes hold about 60% of the load in the same pattern, while improved cylinder chokes distribute around 50% of the shot load in a 76 cm circle at about 23 meters. For precise long-range shots, a full choke is ideal, while for shorter distances, an improved cylinder or cylinder choke allows for greater spread.

Quality and Durability

The Mobilchoke tubes from Beretta are made of robust steel and are marked with colored bands to indicate the constrictions. They undergo a heat treatment to ensure high tensile strength and have a special coating to protect against corrosion. An example of their popularity: The Beretta Mobilchoke Victory Extended 12Ga has a rating of 4.7 out of 5 stars on Amazon based on 87 reviews.

"These are quality Beretta Mobil Choke tubes. I was shopping around for a cylinder tube and the factory tube worked out to be the best value for the money. I've been using this choke intermittently for a year now, and it patterns well, and has broken many clays." – James H., Verified Amazon Purchaser

2. Benelli Crio

The Benelli Crio system was once a benchmark in the world of shotguns but is no longer used in current models. It was mainly applied in the Sport II, Super Sport, and Cordoba models that were released before 2006. The term "Crio" comes from the cryogenic treatment, where steel parts are cooled to extremely low temperatures after manufacturing. Below, you will learn more about the affected models and their performance.

Compatibility with Brands and Models

Earlier versions of the Cordoba, Super Sport, and Sport II models were delivered with Crio chokes and are compatible with them. However, in spring 2006, Benelli USA changed production and introduced Cordoba, Super Sport, and Sport II models with Trulock's Crio Plus instead of the original Crio chokes.

According to Carlson's Choke Tubes, Benelli Crio chokes are about 70 mm long tubes with a thread at the muzzle end. Although they resemble Beretta Optima chokes externally, they are based on different barrel diameters and are therefore not interchangeable.

Performance in Different Shooting Scenarios

Benelli Crio chokes are excellent for various applications such as small game hunting, clay pigeon shooting, and waterfowl hunting. Particularly effective are Kick's High Flyer chokes, which can increase hit density by up to 20% – ideal for hunting distant geese, incoming ducks, or fleeing quails.

An Improved Modified (IM) choke delivers about 65–75% of the shot load within a 76 cm circle at 37 meters. To achieve the best results, it is advisable to try different loads and chokes to find the optimal spread pattern. When using steel shot, a more open choke should be chosen than with lead shot.

Durability and Material Quality

The cryogenic treatment ensures that the steel becomes more homogeneous and resilient. This method improves durability, reduces fouling, and delivers more uniform shot patterns. Many aftermarket chokes are made from 17-4 PH stainless steel, which is particularly corrosion-resistant and increases lifespan compared to standard chokes.

"Crio stands for cryogenic treatment, a process in which steel parts are cooled to extremely low temperatures (often below -300°F, about -184°C) after manufacturing. This intense cold alters the molecular structure of the steel, making it more uniform, denser, and stronger."

Carlson's Choke Tubes for Benelli Crio Plus are extremely popular among shooters. The Skeet version receives 4.9 out of 5 stars based on 32 reviews, while the Turkey version even achieves the highest rating of 5.0 stars based on 11 reviews. An enthusiastic customer, Charles Jorgensen, summarized his experience as follows:

"Amazing choke tubes, durable, clear names on the choke, and the ported extension provides a great shooting experience!" – Charles Jorgensen

To ensure the choke tubes last long, they should be cleaned after each shooting session and treated with some choke grease to prevent seizing. The prices for Benelli Crio chokes range from about €59.99 to €70.00 depending on the model.

On Gunfinder, you can discover a selection of compatible choke tubes for your Benelli shotgun with the Crio system.

3. Browning Invector

The Browning Invector system is one of the established standards for choke tubes and is used in various hunting and shooting disciplines. Browning offers three main variants: Standard Invector, Invector-Plus, and Invector-DS. It is important to know that these models are not compatible with each other. This distinction is particularly crucial when purchasing.

Compatibility with Brands and Models

Browning shotguns marked with "Invector" or "Standard Invector" (including all 10 Gauge, 28 Gauge, and .410 Bore) exclusively use the standard system. For 16 Gauge, the standard system is also mostly used, except for the newer A5 Sweet 16 models, which are equipped with Invector-DS. In multi-caliber sets, Standard Invector (for 16, 28 Gauge, and .410 Bore) and Invector-Plus (for 12 and 20 Gauge) are often used together.

According to Carlson's Choke Tubes, Invector chokes in 12 and 20 Gauge are also compatible with the threads of Winchester, Browning Invector, and Mossberg 500, as these models use the same standard barrel diameter.

Once you have clarified compatibility, the question arises as to how the system performs in practice.

Performance in Different Shooting Scenarios

The Invector system impresses, especially the DS and Plus variants, with consistent spread patterns. This feature makes it ideal for sporting clays, trap, or duck hunting with steel shot. Browning experts emphasize that the system allows for quick and precise hits. The 50/50 POI (Point of Impact) ensures versatile performance.

“With so many different targets, it comes down to personal preference. However, the 50/50 POI shows effective, versatile performance across various sporting clays presentations."

For duck hunting with steel shot, for example with a Browning BPS with Invector-Plus, a Modified or Improved Modified choke is recommended. In trap shooting, the optimal point of impact is at 70/30, while sporting clays are typically shot with a 50/50 POI.

In addition to performance, material quality is also an important factor.

Durability and Material Quality

Carlson's Choke Tubes are made from 17-4 PH stainless steel, known for its corrosion resistance and durability. Aftermarket choke tubes often offer more robust materials than factory models, allowing for tighter spread patterns and more customization options. Some Browning Invector chokes are also made from 17-4 stainless steel.

“Carlson's Choke Tubes are made from the finest corrosion-resistant 17-4 PH stainless steel available. Most factory choke tubes are made from inferior stainless steel, which corresponds to a choke that cannot withstand most steel shot loads or heavy buffered shot shells."

While some users occasionally report rust formation, many manufacturers offer a lifetime warranty. The Invector-DS system uses special technologies for choke constriction, which Browning claims elevate spread pattern performance to a new level.

Suitable choke tubes for your Browning Invector system can be found on Gunfinder – so you are well-equipped for every situation.

4. Remington Rem Choke

The Remington Rem Choke system is a widely used standard, especially in classic Remington models like the Model 870, Model 1100, and Model 11-87.

Compatibility with Brands and Models

It is important to ensure that the barrel has the correct thread, as manufacturers can change their designs at any time.

Performance in Different Shooting Scenarios

The Rem Choke system proves to be extremely versatile and is suitable for both hunting and sport shooting. For sporting clays, it is advisable to use a Modified choke or a combination of Skeet and Modified chokes to achieve consistent and even spread patterns. Carlson's Sporting Clays Choke Tubes for Remington are particularly popular, delivering more precise results than conventional flush-mount chokes due to a 25% longer parallel section. The prices for Remington chokes range from €29.95 for standard flush models to €102.95 for the Spectrum Black Oxide Ported variant.

Durability and Material Quality

Material quality varies between factory and aftermarket chokes. Carlson's Choke Tubes are made from 17-4 PH stainless steel, which is valued for its corrosion resistance. In contrast, many factory choke tubes are made from stainless steel that may not provide the same stability when using steel shot or heavy buffered shot shells.

“Carlson's Choke Tubes made from heat-treated 17-4 PH stainless steel guarantee optimal performance and durability."

Regular cleaning and greasing of the choke tubes is crucial to minimize wear. User reviews on Amazon highlight the quality: Carlson's Choke Tubes for Remington achieve an average rating of 4.6 out of 5 stars.

Community Experiences

In October 2024, Chris King rated a Carlson's Skeet choke with the words: “Works great!”. Such testimonials can help in making a selection.

Important Notes on Compatibility

Manufacturers reserve the right to change their designs without notice. Therefore, it is essential to check compatibility before purchasing. Some manufacturers even use choke tube systems from other manufacturers.

Never force a choke tube into the barrel.

If you are unsure which system your shotgun uses, take a look at the manual, contact the manufacturer, or use online compatibility guides, such as those from Carlson's or Trulock. Platforms like Gunfinder also offer a wide selection of compatible choke tubes for common systems.

Advantages and Disadvantages of Individual Thread Standards

Each thread standard system has its own strengths and weaknesses that affect performance, durability, and user-friendliness. Which system is right for you depends on your individual requirements. Here are the main advantages and disadvantages at a glance.

Design Philosophy and Mechanical Properties

The various systems differ primarily in their construction and function. Longer choke systems like the Benelli Crio or the Beretta Optima score with a thoughtful design. Expert Clyde explains:

I prefer the longer chokes, the Crio at Benelli, which I believe is the same as the Beretta Optima. Mainly because their physical length ensures better alignment in the barrel and places the threads in a less stressed area.

In contrast, Mobil chokes have the disadvantage that the thread is located in the heavily stressed muzzle area:

The original design (the Mobil type) integrated the threaded area (the thinnest area) into the most heavily stressed area, the most constricted muzzle end. If it gives way, stretches, or moves, then that is where it will happen. In my opinion, not the best design to start with.

Performance Comparison of the Systems

The differences between the systems can be summarized well based on their advantages and disadvantages:

Material Quality and Durability

Chokes made from 17-4 PH stainless steel offer significantly higher corrosion resistance compared to standard tubes. They withstand steel shot or heavy loads better and are therefore a popular choice for aftermarket options.

Practical Performance Differences

A particularly impressive example of the performance of certain chokes is the Invector Plus chokes, which can improve pattern density by over 40%. In 2017, the Jebs Headhunter Choke Tube set a record: 35 pellets in a 7.6 cm circle at 40 yards.

Special Application Areas

Optima Plus tubes are specifically designed for use with steel shot and offer better performance compared to standard Optima tubes. Overbored barrels have been developed to improve shot patterns and reduce recoil.

Maintenance and Practical Aspects

Extended choke tubes not only provide tighter patterns but also protect against damage from steel shot. Important to know: Lead loads produce more open patterns than steel loads at the same constriction. The constriction ranges from 0.00 to 1.15 mm, with special turkey chokes even reaching up to 2.50 mm.

Ultimately, it comes down to what you expect from your system – whether it's maximum compatibility, highest performance, or special durability. On Gunfinder, you will find a wide selection of choke tubes for all common systems.

How to Choose and Test the Right Choke Tube Thread

When it comes to choosing the right choke tube thread, there are several factors to consider. The correct thread is crucial to ensure an even shot pattern and to protect the barrel of your shotgun. An incorrect thread can not only cause irregular patterns but also serious damage to the barrel – and that is a safety risk no one wants to take. The first step: Find out which standard fits your weapon.

How to Find the Right Thread Standard

The best starting point is the precise identification of the brand and model of your shotgun. The manufacturer's manual usually contains all the important information regarding the choke tube specifications. If the manual is missing, you can look for markings directly on the barrel.

For example, Beretta shotguns often have markings like “OB” (Optima Bore) or “OB HP” (Optima Bore High Performance). The choke tubes themselves often carry markings like “PB”, “ST”, “SP”, or indications of Optima choke variants. There are various Beretta choke tube systems such as Mobilchoke, Optima-Choke, Optima-Choke Plus, and Optima-Choke HP. Important: These systems are not compatible with each other.

Measuring Threads: When Markings Are Not Enough

If the markings are unclear, you can also measure the threads precisely. Measure the distance from the start of the thread to the end of the tube as well as the main diameter. This can often help you clearly determine the standard. However, with older shotguns, the choke markings may be in a code that can only be deciphered with the help of the manual. Some manufacturers also use a notch system to indicate the choke constriction.

If you are still unsure, contact the manufacturer directly. With the serial number of your shotgun and the barrel serial number, customer service can usually assist you quickly.

Practice: Compatibility and Pattern Testing

Once you have identified the appropriate system, it is important to check compatibility. The choke tube must fit exactly to the brand, model, and caliber of your shotgun to avoid damage.

Pattern tests are essential to test the performance of a choke tube. This checks how the shot material behaves at different distances. Test your choke tubes on paper to gain confidence in your equipment – this pays off in hunting.

A proven method: Shoot at a target with a diameter of 76 cm from a distance of 40 yards. The distribution should capture about 70% of the shot load with a full choke, about 60% with a modified choke, and about 45% with an improved cylinder. A helpful tip: Draw the image of a game animal on the target and check how effectively your shotgun works at your usual distance.

Safety Rules When Testing

When testing, there are some important safety aspects to consider. Never use larger shot sizes with a choke that is tighter than Improved Cylinder. Regularly test at different distances to ensure that the pattern remains optimal and hits where you expect it to. After each use, you should clean the choke tubes to avoid deposits, rust, or dirt.

Sean Weaver puts it succinctly:

“A choke is one of the simplest and cheapest things you can change on a shotgun to improve effectiveness.”

Gunfinder: Everything in One Place

A good starting point for choke tubes is Gunfinder. Here you will find a large selection of choke tubes for almost all thread standards. The platform offers not only new and used chokes from various manufacturers but also accessories like pattern targets or cleaning kits. Knowledge about your shotgun and the cartridges you use is particularly important.

Conclusion

Choosing the right choke tube thread is crucial – you have learned this from the various systems. The different thread standards, such as Beretta Mobilchoke, Browning Invector, or Winchester WinChoke, are not compatible. Using an incorrect or incompatible choke can severely damage the barrel and even lead to dangerous injuries.

"Using Optima-Choke tubes in barrels designed for Optima-Choke HP can result in catastrophic damage to the barrel."

For precise results and optimal performance, the right thread is indispensable. Screw-in choke tubes have fundamentally changed the use of shotguns. They offer shooters the ability to flexibly adapt chokes to the respective situation. For example, a full choke achieves about 70% of the shot load in a 76 cm circle at 37 meters, while an improved cylinder only achieves about 50%.

The correct application begins with the careful identification of the system. For Browning shotguns, for example, there are three different choke tube systems – Standard Invector, Invector-Plus, and Invector-DS – that are not interchangeable. The same applies to Beretta: here, there are Mobilchoke, Optima-Choke, Optima-Choke Plus, and Optima-Choke HP, each with its own standards.

In addition to choosing the right system, regular maintenance also plays an important role. Clean your choke tubes thoroughly after each use to ensure long-term safety and performance. Also, test different chokes with your shotgun to find out which shot pattern best suits your hunting style.

"It's essential to always verify that the choke tube is compatible with your shotgun's barrel before use."

With this knowledge about the various thread standards and their specifics, you are well-prepared to make the right decision for your shotgun.

FAQs

How do I find out if the choke tube thread fits my shotgun?

To ensure that the choke tube thread is compatible with your shotgun, you first need to know the exact thread type of your shotgun. Different manufacturers and models use different standards, such as Browning Invector, Beretta/Benelli Mobil, or Remington.

Check the markings and specifications on the barrel and the choke tube. You will often find helpful hints about the appropriate thread type there. If you are unsure, a look at your shotgun's manual or direct contact with the manufacturer can help. A thorough comparison of this information will save you from making incorrect purchases and ensure that you can use your shotgun safely.

What advantages do longer choke tubes like Benelli Crio or Beretta Optima have over shorter models?

Longer choke tubes like the Benelli Crio or the Beretta Optima provide a more even distribution of the shot load. This improves pattern formation and increases precision, especially for shots at greater distances.

This design shows its strengths especially in demanding shots over long distances. It offers consistently better performance compared to shorter models – precisely when precision makes the difference.

What criteria are important to choose the right choke tube system for your weapon and requirements?

What to Look for When Choosing a Choke Tube System

First, you should ensure that the choke tube system is compatible with the thread standard of your weapon. Different brands and models often have different standards that are not combinable. A close look at your weapon's specifications is therefore essential.

Another crucial point is the shooting distance: Tighter chokes are optimal for long distances, while more open chokes are better suited for shorter ranges. The choice of ammunition also has an impact. Not every choke system is approved for all types of projectiles, such as steel or lead shot. Therefore, always check whether the desired choke system is compatible with your preferred ammunition.

If you are unsure, platforms like Gunfinder can be helpful. There you can search for suitable choke tubes for your weapon and compare different models to make the best choice.
