A semi-automatic rifle is an auto-loading rifle that fires a single cartridge with each pull of the trigger. It uses part of the fired cartridge's energy to eject the case and automatically loads another cartridge into its chamber.[1][2] This is in contrast to bolt-action or lever-action rifles, which will require the user to manually chamber a new round before they can fire again, and fully automatic rifles, which fire continuously until the trigger is released.[3][4]
