What is an AR-10?
The AR-10 is a family of semi-automatic rifles developed by ArmaLite in the 1950s. It is a magazine-fed, gas-operated rifle that is designed for military and civilian use. The AR-10 is similar to the more popular AR-15, but with some key differences.
History of the AR-10

Design and Features
The AR-10 is a gas-operated rifle that uses a direct impingement system, where the gas generated by the fired cartridge is redirected into the rifle’s bolt carrier group, cycling the action and ejecting the spent casing.
