Version 2 geaboxes are best known for M4 gearboxes. They are good because of their extreme availability of aftermarket parts. Because of that, M4s and other V2 variants can be heavily upgraded. Every single part in a V2 gearbox can be upgraded with high end parts that will last for a very long time.
