Our take: The CYMA V7 gearbox is the perfect solution for those who are looking for a powerful, durable yet economical complete M14 full metal drop-in gearbox. This is the standard M14 mechbox that goes into all of the newest CYMA high-powered M14s and M14 SOCOMs. The gearbox comes complete with the CYMA high torque motor, so it is just a matter of plug and play.
This V7 gearbox comes pre-installed with reinforced upgrades including more durable bushings, an M115 spring, a reinforced set of metal gears, and a high-torque motor for perfect performance.
Note: Airsoft Megastore recommends that all internal upgrade be performed by a qualified airsoft technician. Airsoft Megastore is not responsible for damage to your AEG caused by improper installation. Make sure your AEG is compatible with this upgrade component BEFORE purchase. Any upgrades made to an airsoft gun while it is under warranty will VOID the warranty.
