AEG gearboxes and gearbox internal parts are core components of electric airsoft guns. The gearbox is the internal mechanism that contains all the parts required for firing, including the gears, piston, cylinder, and spring.

When the electric motor drives the gear set, the gears pull the piston back against the tension of the spring. Once the piston is released, the spring pushes it forward, compressing air inside the cylinder and propelling the BB through the barrel.

In this category you will find complete AEG gearboxes, gearbox shells, and gearbox internal parts, such as gear sets, pistons, piston heads, cylinders, cylinder heads, tappet plates, bearings, and other gearbox components. These parts are used for maintenance, repairs, and upgrades of electric airsoft guns.

Properly selected gearbox components can improve durability, shot consistency, and overall reliability of the airsoft gun. The selection includes components compatible with various airsoft platforms and common gearbox versions such as Version 2 and Version 3 gearboxes.
