During a rally in Butler, Pennsylvania, former President Donald Trump narrowly escaped serious injury when a shooter fired at him, hitting his ear.

The assailant reportedly used an AR-15.

That rifle — and similar rifles — has become a flashpoint in the gun debate.

But what is it and what does the name mean? (Story continues after gallery.)

What does AR mean?

The AR-15 is a widely-known semi-automatic rifle that has gained notoriety due to its use in various high-profile shooting incidents in the United States. Contrary to popular belief, AR in AR-15 does not stand for “Assault Rifle” but rather “ArmaLite Rifle,” named after the company that first developed it in the 1950s.

Are AR-15 rifles legal?

The AR-15 is legal for civilian ownership in many parts of the United States, prized by gun enthusiasts for its customizable features, accuracy, and ease of use. It has become a symbol in debates over gun control due to its frequent involvement in mass shootings.
