A semi-automatic rifle is a firearm that automatically reloads after firing and discharges a single round of ammunition per trigger pull. It utilizes a portion of the expelled cartridge's energy to eject the spent case and automatically load another cartridge into its chamber.^[1][2] This mechanism differs from bolt-action and lever-action rifles, which require the shooter to manually chamber a new round before they can fire again, and from fully automatic rifles, which continuously fire as long as the trigger remains depressed.^[3][4]
