Ares FF-m rebuild.

[Varjeal]

Looking at doing a complete internal rebuild on an ares ff-m. In this case the only major thing wrong is stripped gears.

I'm looking to sweeten things up compression wise as well as higher quality inner barrel, hopup and perhaps complete mechbox and guts if possible.

What am I looking at as far as proprietary parts?
What brand of internals will provide the best performance for the dollar in this?

Accuracy not ROF is priority. Thanks.

Any reason why you're going balls to the wall with upgrades? I'd say replace the gears and maybe the piston head or cylinder head if they're not sealing well.

Same reason everyone upgrades their gun I guess, better performance, consistency, and in this case better range.

What would be a good choice in terms of brand for the parts you mentioned?
