In some states, building an AR-15 is perfectly legal as long as you follow the necessary regulations and obtain the proper permits. However, in other states, building such a firearm can be illegal.

What Is an AR-15?

Before we get into the legality of building one yourself, let's first define what an AR-15 actually is. Contrary to popular belief, "AR" does not stand for "assault rifle." Rather, it stands for ArmaLite Rifle – named after the company that developed the weapon back in 1959.

The modern-day version of this rifle has become very popular among gun enthusiasts due to its customizability and versatility. However, because of recent mass shootings involving this type of weapon in America over recent years resulting in fatalities many people are calling for stricter gun control laws.
