👉 A binary weapon, also known as a two-way or toggle weapon, is a type of firearm that fires two distinct types of ammunition: one for the barrel and another for the muzzle. This design allows for rapid switching between different calibers or types of ammunition, such as from a standard 9mm to a smaller 5.56x45mm NATO round, or vice versa. This feature enhances versatility and adaptability in various combat scenarios, enabling soldiers to quickly adjust their weapon's configuration without needing to reload or change the barrel. Binary weapons are commonly found in tactical and military contexts, providing a balance between portability and firepower.
