At core, the gearbox contains all the vital parts of an AEG. Most work involved with our team building upgraded AEGs comes from careful modifications and installation of parts our team studies and tests rigorously before implementing within the gearbox.
Our gearboxes are built with an expectation to outperform and last. We aim towards enhancing the Airsoft experience for our customers.
With our gearboxes, we hope to make outperformance much more accessible and convenient for Airsofters, to spend less time working on their gun and more time enjoying it on the field.
Visit our guide to learn step by step how easy it is to install one of our gearboxes into your gun.
Complete your build with an Umbrella Armory R-hop barrel.
