Are you considering purchasing an AR-15? This iconic firearm has gained immense popularity for its versatility, accuracy, and reliability. In this detailed guide, we will explore the history, features, and factors to consider when buying an AR-15.
Origin and History
The AR-15 is a semi-automatic, gas-operated firearm that originated from the AR-10, a 7.62x51mm rifle designed by Eugene Stoner in the early 1950s. The AR-15 was developed by ArmaLite, a company founded by Fairchild Engine and Airplane Corporation. Although the AR-10 was not adopted by the military, its innovative design caught the attention of the United States Army, leading to the development of the M16 rifle.
