Scout rifles are typically bolt-action carbines chambered for .308 Winchester (or 7.62×51mm), less than 1 meter (40 inches) in length, and less than 3 kilograms in weight, with iron and optical sights and fitted with practical slings (such as Ching slings) for shooting and carrying, and capable of hitting man-sized targets out to 450 meters (1,476 feet) without scopes.
