What Is Threaded Barrel?

Are you curious to know what is threaded barrel? You have come to the right place as I am going to tell you everything about threaded barrel in a very simple explanation. Without further discussion let’s begin to know what is threaded barrel?

In the realm of firearms, the threaded barrel is a crucial component that has garnered significant attention and popularity among shooting enthusiasts and professionals alike. But what exactly is a threaded barrel, and why does it hold such importance in the world of firearms? In this blog, we will explore the ins and outs of threaded barrels, their purpose, advantages, and how they have become an essential feature in various shooting applications.

What Is Threaded Barrel?

A threaded barrel is a specialized type of gun barrel featuring external threads at the muzzle end. These precisely machined threads allow the attachment of various muzzle devices, such as suppressors, compensators, flash hiders, and muzzle brakes. The threads are standardized to ensure compatibility with corresponding muzzle devices and accessories, enabling easy interchangeability.

Purpose Of Threaded Barrels

The primary purpose of a threaded barrel is to accommodate muzzle devices, each designed to serve specific functions. Let’s explore some of the common applications of threaded barrels and the muzzle devices they support:

  1. Suppressor Attachment: A suppressor, also known as a silencer, is a device designed to reduce the noise and muzzle flash generated when a firearm is discharged. By screwing a suppressor onto the threaded barrel, the expanding gases from the fired round are redirected and slowed down, leading to a quieter shooting experience.
  2. Compensators and Muzzle Brakes: Compensators and muzzle brakes are devices that help mitigate recoil and muzzle rise during shooting. When attached to a threaded barrel, they redirect gases in a controlled manner, reducing the force and upward movement felt by the shooter, thereby aiding in faster follow-up shots and improved accuracy.
  3. Flash Hiders: Flash hiders are designed to reduce the visible muzzle flash that occurs when firing a gun. By dispersing the burning gases away from the shooter’s field of view, flash hiders improve the shooter’s night vision and minimize the chance of being blinded by the bright flash in low-light conditions.

Advantages Of Threaded Barrels

The inclusion of a threaded barrel offers several advantages to firearm owners and users:

  1. Versatility: Threaded barrels enhance the adaptability of firearms by allowing shooters to switch between various muzzle devices based on their specific needs. Whether it’s reduced recoil, noise suppression, or mitigating muzzle flash, the threaded barrel empowers users to customize their shooting experience.
  2. Recoil Management: Muzzle devices like compensators and muzzle brakes attached to threaded barrels significantly reduce recoil, leading to improved control over the firearm and faster target reacquisition.
  3. Stealth and Safety: With the ability to attach suppressors, threaded barrels enable shooters to reduce the noise produced by gunfire significantly. This is particularly useful for both tactical and recreational shooting, where minimizing noise can be crucial for safety and consideration of neighboring communities.
  4. Enhanced Shooting Experience: By optimizing muzzle rise, flash, and noise, threaded barrels contribute to a more enjoyable and comfortable shooting experience, making it easier for shooters to focus on marksmanship and accuracy.


In conclusion, threaded barrels are an essential feature in the world of firearms, providing shooters with enhanced versatility, recoil management, and an improved shooting experience. With the ability to attach various muzzle devices, such as suppressors, compensators, flash hiders, and muzzle brakes, threaded barrels cater to a wide range of shooting applications, from tactical operations to recreational shooting and competitive sports.

As the demand for customizable firearms continues to grow, threaded barrels are expected to remain a sought-after feature, allowing shooters to optimize their firearms according to their specific needs and preferences. Whether you’re a seasoned shooter or a firearm enthusiast, the threaded barrel is undoubtedly a game-changer, adding a new dimension of functionality and performance to your favorite firearm.

Do You Need Threaded Barrel For Silencer?

As we’ve mentioned, you can put a silencer on a non-threaded barrel. However, threading your non-threaded barrel so you can directly screw on your suppressor is a better option. Why? Attaching a suppressor to a non-threaded barrel requires using an adapter.

What Is The Difference Between A Threaded Barrel And A Rifled Barrel?

The rifling in a barrel (lands and grooves)starts the bullet to spin in a direction which guides it in its flight much like a football spins rather than tumbles. A threaded barrel refers to the exterior threading at the muzzle of the gun made to accept an accessory such as a flash hider or suppressor.

Can Anyone Buy A Threaded Barrel?

Not unless local laws prohibit a threaded barrel. Some attachments may be illegal like suppressors or flash hiders but the barrel itself is probably legal.

Are Most Ar15 Barrels Threaded?

If you want to install any type of muzzle device onto your firearm, you need a threaded barrel. Many kinds of muzzle-mounted accessories exist, such as flash hiders, muzzle brakes, suppressors, and more. Although most AR-15 barrels come out of the factory pre-threaded, not all of them do.
