Collection: Airsoft AEG Gearboxes & Accessories

An airsoft AEG gearbox is to convert electrical energy from a battery into mechanical energy to fire the airsoft gun. It does this by using a motor and a set of gears to compress a spring, which then rapidly pushes a piston to propel a BB out of the barrel. The gearbox also controls the firing mode and cycle, ensuring the BB is loaded correctly for each shot.
