V2 or V3 in a G&G

Hey,
As some of you may know I have recently decided to get the G&G GR 16 A3 tactical carbine. I noticed that the TC has a version 2 mechbox when the gun linked below has a version three. So, what is the difference between the two mechbox's. The reason I dont just go with the V3 is because i really like the looks of the solid stock. Thanks.

V3 is a much more durable design and is much easier to upgrade.

According to mechbox.com, there are NO cons to the gearbox design, other than it is not as many guns.

I'd get the V3, but if it looks matter to you that much, the full stock is great also.

There are only a couple of differences between a V2 and a V3.

A V2 mechbox is known to be weaker in the front of the mechbox, but many companies (G&G, for example) have reinforced gearboxes that usually eliminate that issue. Also, the motor is not mounted to the actual mechbox - making alignment and adjustment more difficult (and reducing overall reliability).


V3 mechboxes are very durable and reliable. It has a solid design that can take loads of abuse. Also, the motor is mounted to the mechbox - making motor alignment very precise (adding to reliability)
