bolt-action
The term bolt action refers to a type of firearm action in which the weapon's bolt is operated manually by the opening and closing of the breech with a small handle, most commonly placed on the right-hand side of the weapon. As the handle is operated, the bolt is unlocked, the breach is opened, the spent shell casing is withdrawn and ejected, and finally a new round/shell (if available) is placed into the breach and the bolt closed. Bolt action firearms are most often rifles, but there are some bolt-action shotguns as well. Examples of this system date back to the 19th century, and except for most sniper rifles and civilian use, have been largly replaced with semi-automatic weapons around the world.
