16 vs 18 vs 20 AR Barrel: A Comprehensive Comparison
When it comes to selecting the perfect barrel for your AR-15 rifle, the choice between a 16-inch, 18-inch, and 20-inch barrel can be quite daunting. Each barrel length offers its own set of advantages and disadvantages, making it essential to understand the nuances of each option. In this article, we will delve into the details of these three barrel lengths, comparing their performance, weight, and overall suitability for various shooting scenarios.
Performance
One of the primary factors to consider when choosing a barrel length is its impact on performance. Generally, a longer barrel provides better accuracy and velocity, while a shorter barrel offers increased mobility and faster follow-up shots.
| Barrel Length | Velocity (fps) | Accuracy |
|---|---|---|
| 16-inch | 2,800 | Good |
| 18-inch | 2,900 | Excellent |
| 20-inch | 3,000 | Outstanding |
As seen in the table above, the 20-inch barrel offers the highest velocity and accuracy, making it an excellent choice for long-range shooting and precision applications. However, the 16-inch barrel provides a good balance between velocity and accuracy, making it suitable for a wide range of shooting scenarios, including hunting and tactical use.
Weight
Another important factor to consider is the weight of the barrel. A heavier barrel can contribute to a more stable platform, but it may also increase the overall weight of the rifle, affecting mobility and handling.
| Barrel Length | Weight (ounces) |
|---|---|
| 16-inch | 1.5 |
| 18-inch | 1.6 |
| 20-inch | 1.7 |
As the table indicates, the weight difference between the three barrel lengths is minimal. However, the 16-inch barrel is the lightest, which can be beneficial for those who prioritize mobility and ease of handling.
Application
The choice of barrel length also depends on the intended application. Here’s a breakdown of the suitability of each barrel length for different scenarios:
- 16-inch barrel: Ideal for close-range combat, hunting, and tactical use. It offers a good balance between performance and mobility.
- 18-inch barrel: Suitable for a wide range of applications, including medium-range shooting, hunting, and tactical use. It provides excellent accuracy and velocity without compromising too much on mobility.
- 20-inch barrel: Best suited for long-range shooting, precision applications, and competition. It offers the highest accuracy and velocity, but at the cost of increased weight and reduced mobility.
Conclusion
In conclusion, the choice between a 16-inch, 18-inch, and 20-inch AR barrel depends on your specific needs and preferences. Consider the performance, weight, and application when making your decision. Whether you’re a hunter, tactical operator, or recreational shooter, selecting the right barrel length can significantly impact your shooting experience.
