    80% of an Umbrella Armory build

    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.

    Don't miss

    Complete your build with an Umbrella Armory R-hop barrel.

    Unlock the most long range effectiveness with increased precision to outrange the competition. Every Airsoft gun we sell comes equipped with an R-hopped barrel set for that reason.
