Battery-powered replicas of military machine guns, designed for recreational war games, typically fire 6mm plastic projectiles. These devices often feature realistic dimensions, weight, and operational mechanisms, such as adjustable hop-up, selectable fire modes, and box magazines. A typical example might include an electrically-driven gearbox propelling BBs at a high rate of fire, mimicking the function of a real firearm in a safe, controlled environment.
These devices play a significant role in simulated military engagements, providing suppressive fire and area denial capabilities for a team. Their simulated firepower adds a layer of realism and strategic depth to airsoft matches, enhancing the immersive experience. Historically, their design has evolved alongside advancements in airsoft technology, mirroring the development of real-world firearms in terms of materials, performance, and features.
