What Size Ammo Does an AR-15 Take?
When it comes to the AR-15, one of the most popular firearms in the United States, understanding the ammunition it takes is crucial. Whether you’re a seasoned shooter or a beginner, knowing the right size of ammunition for your AR-15 is essential for optimal performance and safety. In this article, we will delve into the details of the ammunition that fits an AR-15, covering various aspects such as caliber, types, and common ammunition sizes.
Caliber of an AR-15
The AR-15 is typically chambered in .223 Remington or 5.56x45mm NATO. While these two calibers are often used interchangeably, there are some differences to consider. The .223 Remington is a shorter, lighter round, while the 5.56x45mm NATO is a longer, heavier round. Both calibers are suitable for hunting, target shooting, and self-defense, but they have different ballistics and performance characteristics.
Types of Ammunition for AR-15
There are several types of ammunition available for the AR-15, each with its own advantages and disadvantages. Here are some of the most common types:
-
Full Metal Jacket (FMJ): This is the most common type of ammunition for target shooting and training. FMJ bullets are solid copper or brass, designed to penetrate the target without expanding.
-
Full Metal Jacketed Hollow Point (FMJHP): Similar to FMJ, but with a hollow point tip that expands upon impact, increasing the wound channel and energy transfer.
-
Soft Point (SP): Soft point bullets have a lead core covered by a copper jacket, with a soft nose. They expand upon impact, similar to FMJHP rounds.
-
Expanding Bullet: These bullets have a hollow point or soft nose that expands upon impact, creating a larger wound channel and increased energy transfer.
-
Ballistic Tip (BT): Ballistic tip bullets have a pointed nose and are designed to expand upon impact, similar to expanding bullets.
Common Ammunition Sizes for AR-15
Here is a table showing some of the most common ammunition sizes for the AR-15:
| Caliber | Ammunition Size |
|---|---|
| .223 Remington | 55-grain FMJ, 62-grain FMJHP, 75-grain SP, 77-grain BT, 77-grain FMJ, 80-grain FMJ, 85-grain FMJ, 100-grain FMJ |
| 5.56x45mm NATO | 55-grain FMJ, 62-grain FMJHP, 75-grain SP, 77-grain BT, 77-grain FMJ, 80-grain FMJ, 85-grain FMJ, 100-grain FMJ |
It’s important to note that while these are common ammunition sizes for the AR-15, there may be other sizes available depending on the specific model and manufacturer.
Choosing the Right Ammunition for Your AR-15
Selecting the right ammunition for your AR-15 depends on your intended use. For target shooting and training, FMJ rounds are a great choice due to their affordability and consistent performance. For hunting, expanding bullets like FMJHP, SP, or expanding bullets are recommended for their increased effectiveness on game. For self-defense, it’s best to consult with a firearms expert to determine the best ammunition for your needs.
Conclusion
Understanding the size of ammunition that fits an AR-15 is essential for ensuring optimal performance and safety. By knowing the caliber, types, and common ammunition sizes, you can make informed decisions when selecting ammunition for your AR-15. Always prioritize safety and consult with experts when needed to ensure you’re using the right ammunition for your specific needs.
