The JeffTron Active Brake II is a compact and powerful active braking MOSFET designed to instantly stop the motor after each trigger pull, improving shot consistency and preventing overspin in AEG airsoft replicas. By cutting motor inertia at the end of the firing cycle, this unit helps ensure reliable semi-auto performance and protects internal components from unnecessary stress.
Ideal for both stock and upgraded builds, Active Brake II is especially effective in high-speed or high-voltage setups where overspin can cause double shots or gearbox wear.
