What Length Barrel is Considered an AR Pistol?
The AR pistol is a popular firearm that combines the reliability and durability of the AR-15 platform with the compactness of a pistol. But, what defines an AR pistol? One of the main factors that sets an AR pistol apart from a carbine or rifle is its barrel length. In this article, we’ll explore the definition of an AR pistol and the significance of its barrel length.
Definition of an AR Pistol
The AR pistol is defined as a firearm that consists of a lower receiver and a pistol-length barrel attachment. The lower receiver typically includes the trigger group, magazine well, and handguard, while the barrel attachment is a removable device that allows the user to swap out barrels of various lengths.
Barrel Length and Classification
When it comes to barrel length, the AR pistol can be classified into three categories:
- Pistol-length barrel: 8.5 inches (22 cm) or less in length
- Rifle-length barrel: More than 16 inches (40 cm) in length
- Mid-length barrel: Between 14.5 inches (36.8 cm) and 16 inches (40 cm) in length
Here’s a breakdown of each category:
| Barrel Length | Classification |
|---|---|
| ≤ 8.5 inches (22 cm) | Pistol-length |
| > 16 inches (40 cm) | Rifle-length |
| 14.5-16 inches (36.8-40 cm) | Mid-length |
Significance of Barrel Length
The length of the barrel has significant implications for the overall length and functionality of the firearm. Here are some key points to consider:
• Portability: Shorter barrels (pistol-length) make the AR pistol more compact and easy to carry, making them ideal for concealed carry and urban environments.
• Range and Accuracy: Longer barrels (rifle-length) provide better accuracy and range, making them better suited for target shooting and hunting.
• Weight and Balance: Mid-length barrels offer a balance between portability and range accuracy, making them a popular choice for many users.
Federal Regulations and Length Restrictions
The National Firearms Act (NFA) and the Gun Control Act (GCA) dictate the length restrictions for rifle and pistol barrels. Under the NFA, shotguns and rifles with barrels less than 16 inches (40 cm) or less than 26 inches (66 cm) folded or collapsed are considered illegal. The GCA imposes similar restrictions on pistols.
Taxonomy of AR Pistol Barrels
Some manufacturers categorize their barrels into different lengths, but these categories may not adhere to the traditional definitions listed above. Here are a few examples:
- KAK Industries: The company offers barrels in three lengths: 7 inches (17.8 cm), 10.5 inches (26.7 cm), and 11.5 inches (29.2 cm).
- LWRC: The company offers barrels in two lengths: 7.5 inches (19.1 cm) and 11.5 inches (29.2 cm).
Conclusion
The length of the barrel plays a crucial role in determining the classification and functionality of an AR pistol. With barrel lengths ranging from 7 inches (17.8 cm) to 18 inches (45.7 cm) or more, users have a wide range of options to choose from. By understanding the definition of an AR pistol, the significance of barrel length, and the federal regulations surrounding it, users can make informed decisions when purchasing or building their own AR pistol.
Recommendation
When selecting an AR pistol barrel, consider your intended use, environment, and personal preferences. Here are some recommendations:
• Concealed Carry: Choose a pistol-length barrel (8.5 inches or less) for a compact and lightweight pistol.
• Target Shooting: Opt for a mid-length barrel (14.5-16 inches) for a balance between portability and range accuracy.
• Hunting: Choose a rifle-length barrel (more than 16 inches) for better accuracy and range.
Remember to check local laws and regulations before purchasing or building an AR pistol.
