👉 A coupled weapon is a type of firearm or ammunition system where the barrel and the firing mechanism are integrated into a single component, typically enhancing accuracy, reliability, and compactness. This design often involves the barrel being part of a rifle or pistol, where the bullet's path is guided directly by the rifling (the spiral grooves inside the barrel), ensuring consistent bullet flight. Coupled weapons may also include specialized ammunition like cartridges or bullets that are designed to fit and function optimally within this integrated system, improving overall performance in terms of precision and ease of use.
