Generation of Gearbox?
 

What's the main difference(s) between a 2nd and 3rd generation gearbox, and If you really want to get in depth, the 4th, 5th, and/or 6th generation ones?

Go to mechbox.com...they've got a list there.

Mostly different shapes to fit different the dimensions of different rifles. Some versions use the same parts...others require specific parts.

Are you confusing generation with version?

V2, V3, V6, V7 etc... are all different versions of a gearbox, not necessarily generations as V2 boxes from 10 years ago don't look too different now-a-days. The difference between them is shape so they can fit in different guns. V2 or for M4/M16 and MP5s generally, V6 are for P90 and Thompsons, V7 is for M14 etc...

Sorry, yes I must have confused them. Thanks for clearing it up.
