My suggestion for a build:
Hop-up/Barrel
Madbull Ultimate 3-in-1 Hop-Up
Madbull 6.03 Inner Barrel
Firefly soft hop-up bucking
Internals
High Torque Motor or some sorts- Check
Then I would just recommend a Guarder SP120 FTK, I had one in my AUG a long time back and it made for a nice sub-420 DMR setup. If you are interested in going above 420, then you'll need different parts.
