A carbine is a lightweight, short-barreled firearm that is designed for ease of handling and portability. Typically, carbines are chambered for rifle cartridges, making them effective for various shooting applications, including military, law enforcement, and civilian use. They are often favored for their balance between range and maneuverability. Carbines can be semi-automatic or bolt-action and are commonly used in tactical situations. Many modern carbines, such as the AR-15 and M4, are modular, allowing users to customize them with different accessories like scopes and grips. Their versatility makes them popular among shooters of all skill levels.
