Gearboxes

The gearbox is the heart of an AEG airsoft gun, housing all the key mechanical components such as the gears, piston, cylinder, and spring. Its quality and compatibility directly affect the gun’s reliability, rate of fire, and upgrade potential. In our selection, you will find different gearbox versions, including Ver. 2, Ver. 3, and SR25, as well as reinforced and CNC-machined shells suitable for everything from basic maintenance to demanding upgrade builds.

Whether you are building a new airsoft gun or upgrading an older one, a high-quality gearbox helps ensure reliable operation and long-term durability even under heavy use.
