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