What is the Overall Length of an AR Pistol?
The overall length of an AR pistol is the distance from the end of the buffer tube to the end of the barrel. This measurement is important for determining whether a pistol is legal to own in your state. In most states, an AR pistol must have an overall length of at least 26 inches to be considered a pistol and not a short-barreled rifle (SBR).
There are a few different ways to measure the overall length of an AR pistol. The most accurate way is to use a ruler or tape measure to measure the distance from the end of the buffer tube to the end of the barrel. You can also use a laser rangefinder to measure the distance.
If you are unsure of the overall length of your AR pistol, it is best to consult with a qualified gunsmith.
How to Measure the Overall Length of an AR Pistol
To measure the overall length of an AR pistol, you will need the following tools:
- A ruler or tape measure
- A laser rangefinder (optional)
1. Measure the distance from the end of the buffer tube to the end of the barrel.
The buffer tube is located at the rear of the AR pistol, and the barrel is located at the front. To measure the distance between these two points, place the ruler or tape measure along the side of the pistol and measure from the end of the buffer tube to the end of the barrel.
2. (Optional) Use a laser rangefinder to measure the distance.
If you do not have a ruler or tape measure, you can use a laser rangefinder to measure the overall length of your AR pistol. To do this, point the laser rangefinder at the end of the buffer tube and the end of the barrel. The laser rangefinder will display the distance between these two points.
3. Compare the measurement to the legal requirements for your state.
In most states, an AR pistol must have an overall length of at least 26 inches to be considered a pistol and not a short-barreled rifle (SBR). If your AR pistol has an overall length of less than 26 inches, it is considered an SBR and you will need to register it with the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF).
The overall length of an AR pistol is an important measurement that can determine whether a pistol is legal to own in your state. By following the steps in this guide, you can easily measure the overall length of your AR pistol and ensure that it is legal to own.

3. Common Mistakes When Measuring the Overall Length of an AR Pistol
When measuring the overall length of an AR pistol, it is important to avoid making common mistakes. Here are a few things to keep in mind:
- Don’t measure from the end of the barrel to the end of the buffer tube. The overall length of an AR pistol is measured from the end of the receiver extension (buffer tube) to the end of the barrel. This includes the barrel, the gas system, and the handguard.
- Don’t include the muzzle device in your measurement. The muzzle device, such as a flash suppressor or compensator, is not included in the overall length of an AR pistol.
- Don’t measure the pistol with the stock extended. The overall length of an AR pistol is measured with the stock collapsed. This is because the stock is not considered to be part of the firearm.
If you make any of these mistakes, you may end up with an AR pistol that is not legal to own in your state. It is important to be aware of the legal requirements for overall length in your state before you purchase or build an AR pistol.
