KWA has specific hop units—you really don’t need to change it though. Your hop unit is an unnecessary upgrade 95% of the time for modern AEGs. Keep your stock nozzle. Most of the time it’s fine as well.
Which mags? It depends. The answer is try and see. If you can find someone else with the same gun and hop unit their suggestions might be better, but it’s very individual.
Mags? I know what works for me, but again, what works with your gun is heavily dependent, and I can’t tell you what’ll actually fit right.
Use a silicone hop rubber. Use it all the time. They require almost no “warming up”, and they really have no downsides.
Flat nub and hop rubber are fine, but flat rubbers are notoriously difficult to get perfect. I’d suggest picking something up like a PDI W-hold in a harder degree.
Absolutely no 180 spring. I wouldn’t go higher than M130 on the stock gears, and you need some serious tech skill to keep it together over M140. Even an M130 is really hard on some of those parts you have listed.
You don’t list your hop rubber and nub setup, so I can’t tell you if it’ll handle .40s.
For a battery, I use a $12 butt stock pouch from Amazon, and run a Turnigy Nano Tech 5000 Mah 11.1v in it. Works great, and I never have to worry about underpowering my gun.
KWAs usually aren’t horrible to work, but it looks like you may have had some bad recommendations in your parts choosing. For example, with .30s and a full cylinder your optimum barrel length is about 380mm. And that actually goes down as your BBs get heavier. The overly long barrel may be wrecking your accuracy.
