M4A1 Gen 9 upgrades help please

Hey guys I’ve got an M4A1 gen 9, what stuff am I missing?

I’ve bought the following
Metal gears (shim set and bearings)
Nylon gearbox shell
Stronger return spring
1.3 spring
Green o rings
460 11.1 36000 motor
11.1 battery and charger
Duci head set (8 hole piston head)
Stainless cylinder
Blue ladder
Hop up
33.5 alloy comp barrel with t-piece

looks like you got it all but I would stick with 7.4v
