    I'm fairly new to airsoft and am looking to upgrade my JG M4 S-System, but I don't know what to buy. I've put together a preliminary list on what I think I should get. I'm getting rid of all the stock internals but I don't know what will and won't work. I'm not sure what all goes into the GB and that good stuff.If there is anything that won't fit, work, or you have a better suggestion, I'm all ears. I need a MOSFET and go figure, I don't know any. I would like to have a fire mode converter.So here I go.

    CA V3 7mm reinforced GB

    Well first off your gun has a V2 gearbox not 3 I do believe getting another gearbox shell is excessive if only for a m120, just my 2 cents. So just replace those v3 things with v2. How hot is your gun currently shooting?

    I suppose I'll chime in. First, throw out all of those parts. Systema is bad and over priced. Use your stock spring as it should keep you around 400fps. Grab a Lonex red or blue piston. Grab a Lonex m4 airseal nozzle. The stock Tappet should be fine. Buy some XT connectors, 16 AWG wire, and a MOSFET. If you want an FCU, the BTC Chimera, ACSU, or Cheetah MOSFET are all good. You will need shims, grease, and some CA glue. As for piston head, an element POM or Lonex Pom are good. Grab some 70D Sorbo and a neoprene backer for AOE correction.

    I haven't chronoed yet but I need to be able to use a bigger spring for some fields. And I'll do that Archer.

    Edit: Archer, what websites should I look at? Also my price range is anywhere from $150 - $225 or so, will all the pieces fit my price range?

    Definitely will. Shootercbgear.com, wgcshop.com, Shop.ehobbyasia.com, clandestineairsoft.com, and hivemindairsoft.com are all good places to look.

    No. Lol. An FCU is an abbreviation for Fire Control Unit which is in a MOSFET that is capable of making a gun have burst fire.

    Do any of the websites have everything? I'm only asking to save on shipping and hassle.

    You're not going to be able to get everything on one website.
