👉 A coordination weapon, also known as a coupling weapon, is a type of firearm designed to attach or "couple" two separate firearms together, allowing them to fire simultaneously. This is achieved through a specialized mechanism that connects the barrels of the two guns, often via a common stock or a sliding rail. When the trigger is pulled, both weapons fire at the same time, making it useful for coordinated attacks or in scenarios where synchronization is critical. However, coordination weapons are generally more complex and heavier than single-shot rifles or pistols, and they require precise alignment and secure coupling to function effectively.
