Version 3 gearboxes are best know for AK47s. They are widely considered the best gearboxes considering the ease to work on (attached motor cage) and significantly higher reinforcement versus the version 2 gearbox. Even a stock v3 gearbox can potentially last longer in high impact builds than a v2 would in a normal build. Other than potentially aftermarket SHS and Retro Arms M249 gearboxes, V3 gearboxes are the strongest gearboxes. They are also popular due to the high amount of available upgrade parts. Nearly all internal parts for a V3 gearbox are compatible with V2 parts.
