Parts for an M4 build

So, I recently acquired some CA15 externals in a trade, and I've got some internal parts lying around, so I think I'll do an M4 build.

Here's what I've got:
CA15 metal lower, upper, barrel, RIS, stock, and grip.
Rear SR-25 style flip up sight
CA (I think) V2 gearbox
TM EG700
Marui 455mm inner barrel
Classic Army piston
Spring (M110 I think?)

What I need:
Body pins (Maybe, I might have some lying around)
PEQ box or crane stock
Gears
M4/16 hopup unit (preferably CA)
G3/SG1 cylinder
EDIT: Need a suppressor as well. 200mm should do the trick.

so you still play airsoft?!
jk jk
what kind of gears do you want?

ive got some tm gears and an echo 1 dbalbattery box

How much? Definately interested in the battery box, maybe interested in the gears.

$10 for battery box but since its a DBAL style your gonna need that type of battery which is pretty thin

I have all of that except the PEQ box and crane stock.

^Prices? What brand are the things?

I'm also going to need a 200mm (ish) suppressor.
