How to Measure the Overall Length of an AR Pistol
The AR pistol is a popular choice for many gun enthusiasts, and understanding its overall length is crucial for proper storage, transportation, and compliance with local laws. In this article, we will explore the methods to measure the overall length of an AR pistol.
What is the Overall Length of an AR Pistol?
The overall length of an AR pistol refers to the distance from the front of the magazine well to the end of the muzzle device, excluding any accessories such as a suppressor or muzzle brake. This measurement is critical because it determines whether the pistol is considered a rifle or a pistol under federal law.
Why Measure the Overall Length of an AR Pistol?
Measuring the overall length of an AR pistol is important for several reasons:
• Compliance with Laws: In the United States, the National Firearms Act (NFA) and the Gun Control Act (GCA) regulate the possession and transfer of certain firearms, including short-barreled rifles (SBRs). If an AR pistol exceeds the maximum overall length of 16 inches, it is considered a rifle and subject to NFA regulations.
• Storage and Transportation: Measuring the overall length of an AR pistol ensures that it can be properly stored and transported without exceeding the length limits of containers or vehicles.
• Accuracy and Performance: A longer overall length can affect the accuracy and performance of an AR pistol, particularly when it comes to handling and recoil.
