Is Dboy mauri compatible?

The stock Dboys gearbox is good enough.

Pity you didn't ask this question a week ago. I had a Dboys M4 and a Marui M4 in pieces on my desk. But now I'm too lazy to take them both apart again. If you really want to find out, just bring your gearbox to your friend's place. The Dboys is really easy to break down and pop a new gearbox into.
