Airsoft Gearbox

Airsoft gearboxes and shells

Gearbox is a one of the most important elements of an airsoft electric replica. Every model of AEG (Automatic Electric Gun) replica is equipped with a gearbox, allowing immediate use of the replica on the battlefield. Additionally, the gearbox is an internal part that enables the tuning of an airsoft gun. You can change its individual components or even replace complete gearboxes to improve your model's performance. Understanding the principles of this mechanism is beneficial if you plan to purchase or already own an electric gun replica. This knowledge will assist you not only in operation but also in servicing, tuning, and identifying potential malfunctions.

Airsoft gearbox as an inseparable part of every airsoft gun

The gearbox is a mechanical-electrical system that powers an airsoft gun. It consists of a shell, gears, a trigger with a contact block, a spring, a piston, a cylinder, and a selector switch for changing fire modes. Each of these components is crucial as they set the entire system in motion, allowing you not only to fire BBs from the airsoft gun but also to modify the firing mode, such as achieving single fire, continuous fire, or burst fire. Complete gearboxes are usually purchased with the replica, but they can also be replaced to enhance its capabilities.

Complete gearboxes for your electric airsoft gun

You can equip your airsoft gun with a new, complete gearbox. It must be compatible with your replica, which is why manufacturers always specify the generation or category of replicas it fits. For example, you can choose a gearbox v2 or gearbox v3. These are two airsoft standards that differ in construction but operate in the same way. Pulling the trigger on the replica causes the contacts to close the electrical circuit. The motor is activated and drives the gears, which then pull back the piston. During this time, the spring is compressed, and when the gears complete a full cycle, the piston is released. The expanding spring generates energy and pushes the piston. This compresses the air in the cylinder, which is then directed towards the Hop-Up chamber where the BB is loaded and subsequently fired from the airsoft gun.

Gearbox shell when modifying your replica

The gearbox shell holds all its components together. It is made from various materials: metal or metal alloys, such as zinc and aluminum alloy. The gearbox shell is a crucial element because it endures significant stresses during firing. Therefore, it is worth choosing reinforced shells that can withstand these pressures and allow the use of even stronger springs, which determine the replica's power and performance. A metal shell is more resistant to potential damage, enabling the use of a stronger spring than the one provided by the manufacturer.

Complete gearboxes for popular airsoft guns

Gearboxes are available not only in standard versions like gearbox v2 and v3, but also for specific subcategories of airsoft guns, such as gearboxes for AK replicas. Some manufacturers also create gearboxes dedicated to specific replica lines, so it is essential to select compatible parts carefully. All these gearbox models and their parts are available in our store. They fit both less and more popular airsoft replicas from well-known brands such as Specna Arms, LCT, G&G, Cyma, and Ares.

Choose the best gearbox for your gun!

Replacing the gearbox or its components is one of the steps you can take in tuning the power of your airsoft gun. It is essential to select reinforced elements designed to work with a stronger spring. Investing in products from reputable and proven manufacturers, such as Specna Arms or Prometheus, known for their high-quality parts, is worthwhile. Choosing a gearbox from a popular brand or a basic standard also has the advantage of finding compatible parts easily, which simplifies the process when something in the gearbox needs replacement.
