AEG Gearbox & Accessories
In this category, you will find complete gearboxes from top manufacturers with high quality performance parts. Complete gearboxes are an easy way to upgrade your airsoft guns performance. Reinforced gearboxes are important if you plan on upgrading your gun to have a higher velocity since an upgraded spring usually puts more strain on your stock gearbox and stock gearboxes tend to warp and crack when a high tension spring is installed.
