I'm going to be working on a cyma m14 soon, pretty much going to do a complete tune up. I'm tackling it becuase I want to learn more about version 7s.

I would like to replace the cylinder head, piston, piston head, spring guide and air seal nozzle. I'll probably stick with stock gears, tappet plate and motor until some thing breaks. Maybe swap out the spring depending on the fps output.

Now here is my question, can I use a v2/3 piston, piston head and gears in a version 7 gearbox? I've seen some v7 gears around, but I'm not sure whats up with them. I've also seen version 7 pistons, like the one from Prometheus.

Also is there any thing about v7 gearboxes that I should know when working on them?

Thanks guys, take it easy.
