The term 'long arms' can refer to two different things. The first is a type of firearm, commonly referred to as a rifle. RIFLES are long-barreled firearms that are designed to be fired from the shoulder and have a rifled barrel for increased accuracy. The second is a phrase used to describe someone with unusually long arms, usually in comparison to their body size. This phrase is often used to describe people who are tall or have an above-average arm span.
