The KX 3 Needle is a compact science fiction submachine gun designed for infiltration and close-quarters dominance. It fires 3mm flechette rounds, ultra-dense projectiles that combine speed and precision with devastating lethality. Each round can be wirelessly guided up to 200 meters, ensuring accuracy even in cluttered or obscured environments.

Once a flechette penetrates armor, it deploys three internal blades, tearing through tissue or sensitive mechanical components and causing catastrophic damage. A built-in kinetic suppressor on the forward barrel minimizes recoil and firing signature, allowing operators to remain undetected. The weapon also features a neural interface trigger system, enabling thought-level reaction time and precision.

Lightweight, modular, and brutally efficient, the Needle SMG is a perfect blend of stealth and lethality, feared by both infantry and armored targets alike.
