    Hey, was wondering if anybody could help me out on how to choose the correct parts for upgrading and possibly give some easy to follow tutorials. Right now im looking at when it arrives buying a new motor and possibly spring (or whatever else will increase FPS&ROF). Im not new to airsoft but i am new to upgrading and modifications.

    Motor is easy. Get a high torque or high speed motor and just replace it. Make sure you get the right type, short or long, and make sure you put the connectors on the right way. As for the spring, look up v2 gearbox spring change on YouTube. The other things you will want to do, you can also find on YouTube or search on here, is reshim, correct aoe and grease. Replacing the piston with a polycarb with metal teeth is a good idea as well I'd your going to change the motor and spring

    You're going to want to shim it and grab a 7.4v or 11.1v lipo battery. A G&P m120 motor+ Guarder M110 speing will increase your FPS/ROF as will Swiss cheesing your piston(drill holes through the plastic) and if you want to go all the way grab some high speed gears. Standard ratio is about 18.1, so you'd probably want some 15.1 gears. There's also Tight bore barrels but be careful because a jam at high ROF will be catastrophic.

    I know the gun already has some stuff done to it being custom from evike, nothing to special i'm aware but so far im definitely looking at a spring and a motor and obviously a stronger battery.

    Shimming is where you open up your gear box and add shims to the axles of your gears to let them mesh better and therefore last you longer. Correct AoE is just how your sector gear engages your piston the best way to correct it is by removing the 2nd and possibly 3rd tooth of your piston.
