Revolving rifle

A rifle is a portable long-barrelled firearm designed for precision shooting, to be held with both hands and braced against the shoulder during firing, and with a barrel that has a helical pattern of grooves ("rifling") cut into the bore walls. The term was originally rifled gun, with the word "rifle" referring to the machining process of creating grooving with cutting tools, and is now used for any long handheld device designed for aimed discharge activated by a trigger, such as air rifles and the personnel halting and stimulation response rifle. Rifles are used in warfare, hunting and shooting sports.
