No. The Mossberg 590 and Mossberg 500 shotguns don’t share interchangeable barrels. The barrels from a Mossberg 590 can’t be used on a Mossberg 500 shotgun without any modification.

Firearm enthusiasts and gun owners often encounter questions regarding the compatibility and interchangeability of various components. One common query arises whether a 590 barrel will fit a 500 firearm.

In this article, we delve into the details to provide you with a comprehensive understanding of the compatibility between these two components. Please check our small list below if you have a new Mossberg 590 barrel.

Brief History

Mossberg 500: The Mossberg 500, introduced in 1960, is a versatile pump-action shotgun that quickly gained popularity due to its durability, affordability, and adaptability. It was designed by Carl Benson, an engineer at O.F. Mossberg & Sons, and the design has stood the test of time.

The Mossberg 500 is renowned for its simple yet effective design, making it a favorite among hunters, law enforcement, and civilians. Its modularity and ability to accommodate various barrels, stocks, and accessories have contributed to its enduring popularity.

Mossberg 590: The Mossberg 590, a variant of the Mossberg 500, was introduced to cater to the needs of military and law enforcement agencies. It incorporates enhancements to make it more rugged and suitable for demanding environments.

While the basic design and operation remain similar to the Mossberg 500, the 590 often features improvements such as a thicker barrel, metal trigger guard, and other robust components. The Mossberg 590 series is known for its reliability and has been used by various military and police forces worldwide.

Exploring Compatibility

Let’s explore the compatibility between a Mossberg 590 barrel and a Mossberg 500 shotgun in more detail.

Mossberg 590 and Mossberg 500 shotguns are closely related models, sharing many design elements. Often results in interchangeability between certain parts, including barrels. Unfortunately in this scenario, they are not interchangeable.


While the Mossberg 500 is available with multiple barrel lengths, the 590 is not the same. The 590 is fixed at a 20” barrel length. On the other hand, you will find 18”, 20”, 24”, and various other configurations of the Model 500.

Magazine tube

The main difference between Model 500 and 590 is in the magazine tube. The magazine tubes on Model 500 closed at the muzzle end. The barrel of the gun is held in position by bolting it into a thread at the end of the magazine tube.

On the other hand, the 590 Magazine tube is designed to be open end. The barrel that fits the magazine tube is held into place by a cap nut at the end.

Unfortunately, this reason alone makes it nearly impossible to interchange their barrel. The reason why I said “nearly” is because some people have found ways to replace the magazine tube with a model 500 tube.

If you want to do that, you may require a lot of tools, patience, and money to spare in case you end up destroying two or more 500 and 590’s.
