Ver.3 Cylinder Head/Nozzles - Short? Long?

[Rabbit]

I'm still incredibly green to Ver.3 so you'll these noob posts pop up once in awhile from me Still have a hard time taking in info from outside of ASC and always do so with a grain of salt.

I'm currently building up a CYMA gearbox - i've paid 40$ for it and its a beater but I figure its a great learning platform.

I'm looking at replacing the cylinder head right off the bat along with a few other parts - now when im browsing about i've come across two different kinds, the long cylinder head and the short.

Is there a reason for these two kinds? The original stock cylinder head was a long type, however the actual stock nozzle was surprisingly short and very similar to an M4 type.

Nozzles also come in two different sizes..Do I have to abide by this??

What if I mix and match?

Short answer: AUG and G36 use long cylinder heads. AK's use short.

Quick question on V3 while we are here... FAL uses AK nozzle with short Cyl head correct?
