G36 Question
 

I got a TM G36C... It has a 6.04? or .03? Barrel... and soon to have these uppgrades...

Systema Magnum Motor (Short)
Prometheus air nozzle for G36C
Systema 6mm Oiless Bushings
Systema Silent Head Set VER.III
Systema NEW Polycarbonate Black Piston
Systema Spring Guide with Bearing VER III
Systema Spur Gear Set Original Ratio

Now... I want it to shoot 360ish? maybe 370 what kinda of spring should I put in it to achieve this.

Thanks ^^

6.08mm

A modify M100 will put you in that range if your compression is good.

A Madbull M110 should also land you in your muzzle velocity range.

You would probably be fine with the stock TM spur gear at that power level, a new sector gear might be a good idea though.

The stock TM air nozzle is quite good, no reason to change it.

Curious, why are you putting in a Systema Magnum Motor?

for internal upgrades, just get a Guarder or Prometheus Cylinder Kit, a Prom 100 and new hop-up rubber (medium to hard). soft type sucks. That should put you at about 380 when i had a CA G36K if i recall.

Prometheus M110 spring
systema oiless bushings

thats it, nothing else

I see you are going High ROF better get Deepfire Full metal teeth piston and go with the others said M100 spring will give you 330-360fps.

I am using the Magnum motor because I want high rof and that motor is supposedly one of the best...

I got a Systema Polycarbonate piston.
