A G36C is thought of more as a CQB, or Assault riffle, but what the Hey, we all have our quirks
, I know a player that has tuned his MP5 to M190
, and he laughs because nobody will play against him when he takes it on the field.
So you want to tune the G36 in the direction of 400FPS,
Leave the Modify Modular gear sets alone, when the cage snaps by higher end tuning it also breaks the gearbox by the Cylinder Head.
We are looking at a complete gearbox tuning here,IMHO
Re-enforced Gearbox, don´t play around, buy a 7mm Renforced GB shell, if you want to continue to tune or upgrade later, the box is already there.
Steel bushings, using Oil less, or Oil canal Bushings I would not recommend, they have the tendancy to collect dirt, grime and other junk in the canals, after a little while they will start to grind through the axels of your gears. Bearing bushings are an option here, as long as you are not going to go much higher with your tuning.
Gears, Systema, Prometheus, Super Tourque Up, probably the best mass produced gears on the market for this kind of tuning.
Bore Up cylinder set to include the correct nozzle, don´t forget that you really start to see improvements with FPS starting at the 120er level, anything under that is pretty much a waste of money.
Piston, DeepFire metal tooth piston, I use this Piston in all my tunings, personaly I think it is the best piston on the market.
Piston Head, Deep Fire Bore UP Professional
Tappet Plate, dosn´t need to be replaced
Switch assembly with intergrated MosFet.
Complete new wiring, He is an engineer, he can locate the type of cabel he needs at the local Hobby or Hardware shop.
Tuning Barrel, you can put in one from LayLax, Prometheus, or DHC, but in my opinion, for a short barrel it is a waste of money, a Mad Bull tuning Barrel would be more than enough and you can save alot of $$.
Hop-Up, replace it with a harder rubber, The MadBull shark comes with both the soft silicon rubber which I find to be excellent up to the 120er level, after that the hard rubber works great for pretty much all higher end tunings.
Spring and Spring Guide, I would go for the HAPPY MIDDLE, a Mad Bull 130, just make sure that you pump a few Hi-CAP magazines throught the rifle first before you measure the FPS, this springs require a little break in before you measure them. Spring Guide, Metal, enough said.
Motor, there is no question here, a Systema, High Speed or Magnum to include a new Pinion gear, the standard Pinion gear that comes on the motor won´t last long, replace it with a Chrom-Molybdän Steel Pinion Gear.
Replace the connectors with Deans, and make the change to Large Type Batteries, 9,6V 3000Mah, the Systema motors are great, but they are electricity pigs !!
Some nicities to keep in mind,
Sector Clip
Polishing your GB
Teflon Tape on the cylinder Head
Teflon Tape on the Hop Up
Robbe Gear Grease ( Local Model ( RC ) Shop )
Silicon Oil
Don´t forget to break in your Gears, and Motor before you complete the building of your GB, will save you some hassle later on.
All my reccomendations are based on the Idea that you will be continueing with the tuning later on, but if you decide to stay at the 400FPS level, this GB will give you no problems.
Just hope you are not going to be using this for CQB, you are going to hurt someone.
Happy Tuning
