300 Blackout Barrels: An Overview


When it comes to building or customizing a rifle, one of the most important components to consider is the barrel. The barrel determines the accuracy, velocity, and overall performance of your rifle, and it's crucial to choose one that meets your specific needs. If you're considering building a rifle chambered in 300 blackout, you'll want to invest in a high-quality 300 blackout barrel.

But with so many options on the market, how do you know which barrel is the best choice for your rifle? In this blog post, we'll provide an overview of 300 blackout barrels and discuss some of the key factors to consider when choosing one for your rifle.

What is 300 Blackout?


Before diving into 300 blackout barrels, it's important to understand what 300 blackout is and how it differs from other cartridge options. 300 blackout, also known as 300 BLK or 7.62x35mm, is a relatively new cartridge that was developed by Advanced Armament Corporation (AAC) in conjunction with Remington Defense. It was designed to be used with a standard AR-15 lower receiver and magazine, making it an attractive option for shooters who want a rifle that is compatible with their existing AR-15 parts and accessories.

300 blackout was created to fill the gap between 5.56mm NATO and 7.62mm NATO cartridges. It offers similar ballistics to the 7.62x39mm cartridge used in the AK-47, but it can be fired through an AR-15 platform with minimal modifications. This makes it an ideal choice for those who want the power and versatility of the 7.62x39mm cartridge, but with the added benefit of being able to use their existing AR-15 parts and accessories.

Types of 300 Blackout Barrels


When it comes to 300 blackout barrels, there are several different types to choose from. Some of the most popular options include:

Cold hammer-forged barrels: These barrels are made using a process called cold hammer forging, in which a mandrel is forced through a barrel blank to create rifling. This process is known for producing barrels with excellent accuracy and durability, making them a popular choice for military and law enforcement applications.

Stainless steel barrels: Stainless steel barrels are highly corrosion-resistant and offer excellent accuracy and durability. They are also easier to clean and maintain, making them a popular choice for shooters who plan on using their rifles in harsh or humid environments.

Carbon fiber barrels: Carbon fiber barrels are made using a composite material that is lightweight and strong. They offer excellent accuracy and are significantly lighter than traditional barrels, making them a popular choice for shooters who value portability and maneuverability.


When choosing a 300 blackout barrel, there are several key factors to consider. These include:

Length: The length of the barrel will affect the velocity and accuracy of the cartridge. In general, longer barrels tend to offer better accuracy, but they also add weight and decrease maneuverability. Shorter barrels, on the other hand, are more portable and easier to handle, but they may sacrifice some accuracy.

Twist rate: The twist rate refers to the number of inches the bullet travels for each complete revolution of the rifling. A higher twist rate (e.g. 1:7) is better for stabilizing heavy bullets, while a lower twist rate (e.g. 1:9) is better for lighter bullets. It's important to choose a barrel with a twist rate that is appropriate for the type of bullets you plan on using.

Material: As mentioned above, 300 blackout barrels are available in a variety of materials, including cold hammer-forged steel, stainless steel, and carbon fiber. Each material has its own unique properties and benefits, so it's important to consider which one is the best fit for your needs. For example, stainless steel barrels are highly corrosion-resistant and durable, making them a good choice for shooters who plan on using their rifle in harsh environments. Carbon fiber barrels, on the other hand, are lightweight and strong, making them a popular choice for shooters who value portability and maneuverability.

Brand: It's important to choose a reputable brand when purchasing a 300 blackout barrel. Look for brands that have a proven track record of producing high-quality barrels with excellent accuracy and durability. Don't be afraid to do some research and read reviews from other shooters before making a decision.

Price: Of course, price is also an important factor to consider when choosing a 300 blackout barrel. There is a wide range of prices on the market, and it's up to you to decide how much you are willing to spend. Just keep in mind that a higher price doesn't always equate to better quality, so be sure to do your research and consider all of the other factors before making a decision.
