First, don't double post. Second, why are you asking us if you already ordered all of those parts. Third, you already have another thread like this one where you easily could have posted in.
Angle custom aeg tight bore (Angle is not a brand. Angel is. And I would reccomend it if it weren't so expensive. I strongly suggest you go with a Prometheus barrel.)
5ku gbb to aeg barrel hop up conversion kit (No.)
5ku adjustable npas (No.)
SA steel bearing hammer (Stop listing chinese parts.)
5ku steel bolt stop base-------------ordered
5ku cnc steel sear-------------------ordered
Element steel selector----------------ordered
Element steel trigger-----------------ordered
Iron Airsoft cnc aluminum bolt carrier---ordered (This is good.)
5ku aluminum speed buffer-------------------ordered
Bioval or Golden ball .30 or .36 gram bbs
You listed a lot of 7-10 dollar chinese parts. That's a huge no-no, because not only does it reduce resale value by a ton (they are pretty much considered worthless), they break rather easily, steel or not, due to bad tolerances and the material they use (It's probably worse than 1018 steel.).
I recommend LCT parts and IRON airsoft parts.
You will also want a new loading nozzle. Go with IRON aluminium nozzle.
If you ever get the chance, replace your trigger set with a G&P steel one.
