20 Inch AR-15 Barrel: A Comprehensive Guide

When it comes to customizing your AR-15 rifle, one of the most significant upgrades you can make is to replace the factory barrel with a 20-inch model. This article will delve into the various aspects of a 20-inch AR-15 barrel, including its benefits, considerations, and how it compares to other barrel lengths.

Benefits of a 20 Inch AR-15 Barrel

One of the primary advantages of a 20-inch barrel is the increased velocity it provides. A longer barrel allows for more time for the bullet to accelerate, resulting in higher muzzle velocity. This can be particularly beneficial for hunting or tactical scenarios where increased range and penetration are desired.

Additionally, a 20-inch barrel offers a more balanced feel to the rifle. The extra weight in the barrel helps to counterbalance the lighter receiver, making the rifle more comfortable to shoot for extended periods. This can be especially important for those who plan on engaging in long-range shooting or competitive shooting events.

Considerations for a 20 Inch AR-15 Barrel

While a 20-inch barrel offers numerous benefits, there are also some considerations to keep in mind. One of the most important factors is the ammunition compatibility. Not all ammunition will perform optimally with a 20-inch barrel, so it’s essential to test and ensure that your chosen rounds are suitable for this barrel length.

Another consideration is the overall length of the rifle. A 20-inch barrel will increase the overall length of your AR-15, which may affect its handling and storage. It’s important to ensure that the rifle still fits comfortably in your vehicle or storage space.

Additionally, a 20-inch barrel may require a different gas system than the factory barrel. This is because the increased barrel length can lead to higher gas pressures, which may require a different gas port size or a different gas block altogether.

Comparison with Other Barrel Lengths

When comparing a 20-inch barrel to other barrel lengths, such as a 16-inch or 18-inch barrel, there are several factors to consider. A 16-inch barrel is typically the shortest legal length for an AR-15 rifle, making it a popular choice for concealed carry and home defense applications. However, it offers lower velocity and range compared to a 20-inch barrel.

An 18-inch barrel strikes a balance between velocity and overall length. It provides a good compromise between increased range and the convenience of a shorter rifle. However, it may still lack the velocity and range of a 20-inch barrel.

When comparing a 20-inch barrel to a 24-inch barrel, the main difference is the increased velocity and range. A 24-inch barrel is often used for long-range shooting and hunting applications. However, it may be heavier and more cumbersome to handle, especially for those who prefer a lighter, more compact rifle.

Choosing the Right 20 Inch AR-15 Barrel

When selecting a 20-inch AR-15 barrel, there are several factors to consider to ensure you choose the right one for your needs. Here are some key points to keep in mind:

Material: Choose a barrel made from high-quality materials such as stainless steel or carbon steel for durability and corrosion resistance.
Profile: Consider the barrel profile, which can affect the rifle’s balance and handling. A lightweight profile can make the rifle more maneuverable, while a heavier profile can provide better stability.
Twist Rate: The twist rate determines how well the barrel stabilizes the bullet. A 1:7 twist rate is suitable for most ammunition, while a 1:8 or 1:9 twist rate may be better for heavier bullets.
Barrel Thread: Ensure that the barrel has the correct thread pattern for your rifle’s gas system and accessories.

By considering these factors, you can select a 20-inch AR-15 barrel that meets your specific needs and preferences.

Conclusion

In conclusion, a 20-inch AR-15 barrel offers numerous benefits, including increased velocity, a more balanced feel, and improved range. However, it’s important to consider the potential drawbacks, such as ammunition compatibility and overall length. By carefully selecting the right barrel for your needs, you can enhance your AR-15 rifle’s performance and enjoyment.
