Upgrading a G&G m4
 

So i got my G&G R4 Commando and was looking to upgrade the internals. I'm looking for about 380 FPS and Good compression and accuracy.
I was looking at getting a G&P metal hop-up,
Madbull 6.03 363mm inner barrel,
Modify Pistion head Cylinder head and nozzel,
Prometheis m110 spring
and a sorbo pad
but then i thought is that all really needed and thought to check here first any input is welcome Thanks

Forgot about the most important part... A piston head!

I'd recommend getting the ARS MASK piston head (POM) and the ARS MASK cylinder head. They're fantastic :)

u might have just missed it but thanks for the recommendation

Yup, totally did miss it. Whoops!

But he DID forget Guarder clear hopup rubber and Shredders spacer!

If you are going to do all this... make sure you have a GOOD battery with good connectors. The last thing you want is not having the right amount of juice to pull that 110 spring and burn your motor.

ya i already have a G&P 9.6v 2300mah battery with deans
