In the 1957 Eugene Stoner developed the AR15/M16 rifle that shoots the .223 Remington/5.56 NATO caliber rounds. The design of this rifle utilizes the gases that push the bullet down the barrel to cycle the action of the semi-automatic and full-automatic AR15/M16 rifle.

 These gases are vented into a gas tube through a hole on the barrel (the gas port). The gases travel back toward the receiver of the firearm and use its pressure to push the bolt carrier backwards toward the stock of the rifle.

This rearward movement of the bolt carrier rotates the bolt out of chamber (by utilizing the cam pin and cam pin channel) which will eject the empty casing of the fired round. The bolt carrier travels against a buffer and spring in the buffer extension tube (located inside the stock) just behind the receiver.
