A BB, commonly used in airsoft and BB guns, is typically made of plastic or steel. Plastic BBs are often made from materials like polyethylene, while steel BBs are usually coated to prevent rusting. The size of a BB is standardized at 6mm for airsoft and 4.5mm for steel BBs used in air guns. These materials ensure durability and consistent performance in shooting games.
