Hey guys, I want to do a build by myself on a gun.
Right now I have a G&G Cm16 raider and its all stock except with a super upgraded Madbull barrel. I want it to shoot 675 fps and not spend a lot of money. Also, I'm afraid of lipos so it has to be on a 9.6 at most.
What I have so far:
Stock most everything M190 Spring, matrix Super high speed motor Fps up Tappet plate 1:16 Gears Matrix bearings 6mm
Everything else is stock. I'm not going to shim it because it's hard and doesn't really do much. I'll do all the compression mods with loctite and I might do a mod I was designing where you stand off the outer part of the piston O ring so that it returns faster for more rps.
Is everything okay?

What do you plan on doing with this gun if/when you complete it. It will not be allowed to be used at ANY MiA or national event. We are in this to have fun, not to seriously injure people.
Anyone that knowingly takes a gun shooting at that power and points it at another human being is only out to put airsoft in the news in a bad way, and ruin the sport for everyone. High FPS does not make any airsoft gun better than another. And if it is range you are trying to accomplish there are much better ways of achieving longer range without endangering other players. FPS does not directly correlate to range, there are many other factors. You can hit long ranges with a properly set up gun shooting 350fps or lower.
Can a stock gearbox and components even handle a M190 spring for any appreciable lifespan?

Gonna be honest, my troll senses are tingling on this one.
However, if they aren't, I'm just going to suggest you drop this build. As Zzan said, you won't be able to use it at ANY sanctioned event, and if you use it in backyard games, you are likely to hurt someone. Airsoft doesn't need that kind of bad exposure.

Shimming is most definitely not hard and it's incredibly important to do. Don't shim your GB and throw in all those parts, see how long it lasts. M190 spring? Are you nuts dude? I say let him do it because there's no way this gun will still be functioning when he tries to take it to a game. And even if it does work, there's no way anyone will be willing to play with him.
Your current build is far from appropriate and fieldable. Shoot us some ideas of what kind of performance you're looking for, and we will be more than happy to lead you to a much more practical and acceptable setup.

So what would be good parts to use to make it a good gun for under $76.43? That's what I have. I want it so shoot hard so that people know that they get hit and shoot fast too like at least 35 rps.

If you're looking for an incredibly high fire rate (That personally I would NOT advise doing) you are not going to want a hard hitter. I'm pretty sure someone will be able to notice 35 rounds coming at them. Abandon the high FPS idea, and personally I wouldn't field a gun shooting over ~350 FPS with that fire rate, because not only is it unnecessary, it's dangerous and will piss off a LOT people. Not to mention that your internals will be obliterated very quickly. You'd be lucky if the gun survived through an entire day to be honest.

So how about a matrix high speed motor, high speed gears like 1:13, and then a m90 spring.

Looking better. Would you consider a complete gearbox swap? For 85 bucks you can pick up a complete G&P V2 gearbox that will drop right in, and will give you a MASSIVE increase in performance over the G&Gs CM line. I personally went this route with my DBOYS SCAR because literally every single part that would be replaced by a G&P part would be a massive upgrade. 8mm bearings are a very nice touch too. I paired this gearbox with a G&P M120 motor and a 7.4v lipo and I'm getting at least over 20 RPS at 340 FPS, haven't tested the ROF, but it's more than enough. I posted a video a while ago when I did the swap, so you can check it out and see if the performance is what you're looking for.

You will definitely want to stay away from high speed motors, they not only run very inefficient, but the torque rating is very low. 13:1 gears are a great option for torque and speed, but with a high speed motor and a low ratio gear set you will be reaching a very high rps. With that being said, you will want a stiffer spring and probably to short stroke a few teeth to avoid pme and keep the fps down. I run 40rps at 400fps just fine with no issues. In fact, I consider my gun to be more reliable than a stock gun. Please come back to us with a full parts list, as high speed gears and a high speed motor will shred any stock gearbox.

I think its pretty cool that you guys are able to pull off insanely high ROF rates, but from a practical perspective, what is the purpose of this? It only takes one BB to tag a person. Don't take this the wrong way, I'm just confused as to why everyone now a days wants an overkill and unrealistic rate of fire. I remember wayyyy back in the day when 18 RPS was considered super fast.

So you're gonna need a lipo to increase your FPS that much, an aluminum piston to increase power, bore up cylinder to increase rof, and a speed trigger for more rof... just kidding... First of all I would not recommend jumping into a relatively high performance build as your first one. You obviously have no teching experience if you don't even want to shim your gun, which is definitely something you need to do if you want to increase performance. If you have another AEG you might want to practice shimming, AOE correction, and fixing airseal before you ruin your primary gun. Iif you want that ROF with an "acceptable" CQB FPS you're going to want 13:1 gears, a high-torque motor, a mosfet, M120 spirng (short stroked) and a lipo. Speed motors are pretty unnecessary for high speed or really any build, when you can use neodymium magnet high torque motors. Go with a SHS high torque (or anything 16 TPA) for higher speed or a ZCI high torque (or anything 22 TPA) for slightly less speed and better trigger response. Also you might need to short stroke it if you want to have a lower FPS otherwise you could have pre-engagement (which is bad). This means DO NOT use an M90 spring, use an M120 and cut teeth off the piston and sector gear to lower FPS. Honestly, there are tons of threads just like this one with someone asking how to do a high speed build. Just Google search, please. EDIT: myers: high rof is just for the swag . No but really, some people just do it for the intimidation factor. In terms of practicality, a higher volume of fire definitely will increase your chance of hitting someone at the edge of your gun's effective range. I'm not condoning high rof full auto gameplay, but it's something to consider.

People will know they have been hit at 350 FPS. If they don't acknowledge it then they are cheating, nothing you can do about that except find more honest people to play with. Of course a good number of instances where people are accused of not calling hits, they aren't getting hit, the shooter just isn't as good or doesn't have the range they think they do.
Honestly a good Hop-Up, Flat-Hop or R-Hop modification, and good compression can go a long way.
I only have a M100 spring in my gun and it shoots at 375 FPS with .20's. I also have an R-hopped 6.02 363mm inner barrel, a Modify metal hopup unit, and a fully shimmed and tuned G&P gearbox with excellent compression and I can reach out to 200+ ft accurately.
If you want a good gun start with the hopup, inner barrel and gearbox tuning. Shimming does have a noticeable effect on the consistency of your shots as well as making your gearbox more quiet when done properly, as well as extends the life of your gears and piston teeth.
If you truly need that high of a rate of fire (which is again frowned upon, but not illegal if in the right FPS range - depending on event rules) then you are going to need a battery capable of sustaining a high discharge rate.
There really isn't any reason for high automatic fire rates unless you are using it for bragging rights. There is no reason to have 70 BB's in the air at once for a 2 second burst and seriously over-killing someone. It will only cause problems and possibly get you punched in the face by the person receiving the BB's. Most people that wish this kind of a setup are younger and use full auto to compensate for skill, or just don't understand how it works/feels to be on the other end. A single BB gets a kill.

I'll just buy a G&G gearbox and put it in there so that i know it will fit. Then I'll get a lipo and make it shoot fast. Would a Classic Army high torque motor be good?

Make sure you pick up a G&P gearbox, not a G&G. You want this one, or if your gun is front wired, this one. I personally steer clear from CA products, but that's just me being biased from getting an absolute lemon from CA in the late 2000s. I've heard Lonex motors are pretty good if you're not interested in a G&P.

Which Lonex motor do I get? The A5 looks like it would be good for the price?
And my gun is a G&G not a G&P, would it fit?
