The term 'long-barreled weapon' can be summarized as a RIFLE, which is a five-letter word. A RIFLE is a type of firearm that has a long barrel and is designed to be fired from the shoulder. It is typically used for hunting or target shooting, and is also used by the military. Rifles are usually made of metal and have a rifled bore, which is a series of grooves inside the barrel that spin the bullet and give it greater accuracy and range.
