Automatic shotguns are firearms that can fire multiple rounds with a single pull of the trigger. They use the energy from the fired shell to automatically cycle the action, ejecting the spent shell and loading a new one. This allows for rapid firing, making them popular for various applications, including hunting and sport shooting. These shotguns typically use a magazine to hold multiple shells, which can vary in capacity. Some models are designed for specific uses, such as tactical operations or competitive shooting, and may feature accessories like pistol grips or picatinny rails for mounting optics and other equipment.
