Fifty Years and Counting for the AR-15

Designed by Eugene Stoner in 1957, the AR-15 has been used in service since 1958. It entered the U.S. military system as the M16 rifle in 1963, though today semi-automatic versions are still referred to as the AR-15. Originally built by ArmaLite (hence the "AR") and sold to Colt, there have since been many AR-15 manufacturers including Sig Sauer, Remington Arms and Smith & Wesson. Here at GunBroker.com, modern AR-15 models are for sale and are relied on by civilian shooters and police forces, while those no longer in-use are added to gun collections or stowed away. As lightweight semi-automatic rifles, AR-15s are known for their accuracy and ergonomic design that makes them easy to assemble. AR-15s are also flexible weapons that can be switched to long-range rifles simply by swapping upper receivers, and they are a cinch to fix and maintain because their parts are available worldwide.
