What id did was add
Madbull steel fill valves
Ratech npas for kjw m4
Tsc steel internals
Falcon extended inner barrel
Falcon 60 degree rubber
Small mods.

Will try for more, but that is so far. Will update if it gets better!

Please elaborate on the "small mods" portion. If you are trying to help someone else out, be more detailed. Otherwise it does us no good.
