I have been looking all over for a good cqc gun and I saw this on sale for $100 and I just could not say no: http://www.evike.com/product_info.php?cPath=21_217_497&products_id=30825 I read that the base gun is pretty good and upgradeable. I want high rps, good range (better then is necessary for cqc), and of course there is no point in these without accuracy. Since this is my first ever upgrade I want to start slow and easy. I'll start with shimming and possibly AoE. Where I get lost, and hopefully you awesome Techs can help me out, is picking out things such as motors, gears, springs, MOSFETs, and any other parts that I have left out. I have read through a few of these upgrade help threads and when I try to look for parts myself I get overwhelmed by all the choices and manufacturers. So please when you suggest a part please link me it. I went ahead and tried to find some of the parts. Tell me what you guys think. spring http://www.evike.com/product_info.php?products_id=31454 spring guide http://www.evike.com/product_info.php?products_id=35850 gears http://www.evike.com/product_info.php?products_id=32916 motor http://www.evike.com/product_info.php?products_id=25608 MOSFET http://www.hhairsoft.com/Products/Custom_MOSFET_Units/HH-02.html wire ?
