Our take: The CYMA V3 gearbox is a drop-in solution for those who are looking for a reliable yet economic complete AK replacement gearbox. This is the standard V3 that goes into all of the newest CYMA high-powered AK47s, and is solidly built.
This V3 gearbox comes complete with high-performance upgrades including more durable bushings, an M115 spring, a reinforced high torque metal gears, and a high-torque motor. Ultimately, it's a reinforced drop in V3 metal gearbox in every way, EXCEPT it's at an unbeatable price.
