Understanding Chokes: What They Do and Why They Matter

When learning about shotguns, one of the most important components to understand is the choke. While it may be a small part of the overall firearm, the choke plays an important role in controlling how the shot pattern leaves the barrel.

For anyone exploring the Revolution Armory lineup, understanding the basics of choke tubes can make it easier to understand the specifications of different models and how their included chokes can be used.

What Is a Choke?

A choke is a constriction at the muzzle end of a shotgun barrel. This constriction helps control the spread of the shot after it leaves the barrel.

Different choke tubes provide different levels of constriction. In general, a tighter choke produces a more concentrated pattern, while a more open choke allows the shot to spread more quickly.

Revolution Armory models may be supplied with multiple choke tubes, giving the shooter options depending on the firearm’s configuration and intended application.

Common Choke Types

Chokes are commonly identified by names that describe their level of constriction. Some of the most familiar include:

Cylinder

Cylinder is one of the more open choke options, with little or no constriction. It allows the shot to spread more quickly after leaving the barrel.

Improved Cylinder

Improved Cylinder provides slightly more constriction than Cylinder while remaining relatively open. It can provide a useful balance between spread and pattern density.

Modified

Modified provides more constriction than Improved Cylinder. It produces a tighter pattern and is a commonly encountered choke option.

Improved Modified

Improved Modified provides more constriction than Modified, resulting in a tighter pattern.

Full

Full is one of the tighter commonly used choke options. Its greater constriction is intended to produce a more concentrated shot pattern.

Skeet

Skeet is an open choke designed for applications where a wider shot pattern is desirable.

Why Do Different Chokes Matter?

Shot does not leave the barrel as one solid projectile. Instead, a shotshell releases a group of pellets that begin spreading as they travel.

The choke influences how quickly that pattern opens up. Choosing between different choke tubes can therefore change the pattern characteristics of the firearm.

This is why many shotguns are supplied with interchangeable choke tubes. Rather than having one fixed configuration, the shooter can select an appropriate choke from the options supplied with the firearm.

Choke Selection and Shot Type

One important consideration is the type of shot being used.

According to the Revolution Armory choke guide, lead shot can be used in all sizes of choke tubes, while steel shot is only recommended in Modified, Improved Cylinder, and Skeet choke tubes.

Always consult the manufacturer’s documentation for the specific firearm and choke tubes before selecting ammunition. Choke and ammunition compatibility should never be assumed.

Understanding Chokes on Revolution Armory Firearms

Several Revolution Armory models feature interchangeable choke systems, allowing users to work with different choke configurations.

For example, the K18S 12GA Over/Under is supplied with five Mobil choke tubes:

  • Full

  • Improved Modified

  • Modified

  • Improved Cylinder

  • Cylinder

Having multiple options gives the user the ability to select from a range of choke configurations rather than being limited to a single fixed choke.

Other Revolution Armory models may include a different selection of choke tubes, so it is important to check the specifications for the individual model.

The Importance of Patterning

Understanding what a choke is designed to do is only part of the equation. Patterning can help demonstrate how a particular firearm, choke, and ammunition combination performs together.

Because patterns can vary depending on the firearm, choke, ammunition, and other factors, shooters should follow appropriate range and safety procedures and use the manufacturer’s recommendations when evaluating their setup.

Choosing the Right Choke

There is no single choke that is ideal for every situation. Different choke configurations offer different pattern characteristics, which is why understanding the available options is useful.

When looking at a Revolution Armory shotgun, take the time to review:

• The included choke tubes
Check which choke options are supplied with the specific model.

• The firearm’s specifications
Barrel length, gauge, action, and other design features all contribute to the overall configuration.

• Your ammunition
Make sure your chosen ammunition is appropriate for the firearm and choke combination.

• Manufacturer recommendations
Always follow the manufacturer’s instructions and compatibility guidelines.
