I am upgrading my cyma v3 ak47 and I need some help. I want to upgrade the spring to a M120, spring guide to one with a bearing and new metal bushings. Only problem is I just don't know,what size bushings I need?I think I need 6mm but, I don't really know. This is my first time upgradng and I don't have anyone close by to do it for me. I think I can handle it from the countless hours on YouTube to be able to get it done.

Since this is the first time you'll be upgrading there are a few thing you'll want to consider. Why exactly are you upgrading? What issues are you having currently that you think a new M120, bushings, and a spring guide will solve?
If this is currently your only gun at the moment, I would stray away from upgrading. It's not as hard as it seems, but your first time takes a lot more patience than when you're more used to the insides of your gearbox.
It's usually much easier to get a used gearbox and toy around with it, so that in case you mess up your only gun at the moment isn't benched until you harness your upgrading skills.
I'd probably say CYMA bushings are either 6mm or 7mm, I don't think CYMA uses 8mm, but I could be wrong. If the stock ones are plastic, 99% sure they'll be 6mm. The easiest thing to do is measure them when the gearbox is out side of the body. It's pretty easy to see the difference between 6, 7, and 8.

OK yeah ,this is my only gun but,it has low fps like 330ish (according to the box never been chronograph ed)I want 400ish so it will good at field and I was told if I want to change springs I need a new spring guide and bushings but I don't want to mess any thing up and i have only had the gun for 3 days and I'm on a very tight budget so I cant get a used gearbox.So If I attempt this I should take apart my gun first before I order my part?

I'm saying it'd be easier to work on something that's already torn apart (like a used gearbox) instead of opening the only gun's gearbox that you have and "attempting" to upgrade it and it possibly not working out. I know from experience, from when I first started, that having your only gun on the bench suck.
You'll have to get down to your gearbox anyhow to figure out what size bushings you have before you order new metal ones and them turning to be the wrong sized ones.
First time and tight budget very rarely go hand in hand together well.

Forget the spring upgrade, it really won't help anything. I'd say stay out of the gearbox for now and focus on the barrel and hop up. Adding extra FPS won't do you any good without proper consistency.

okay, chances are your box will say 338 fps. This is because it's illegal to ship anything over that. if its a clone, it's probably friring around 160... so I'd actually chrono it...

Since when is it illegal to ship anything over 338fps? This is your gun, correct? I ask this because it's quite different than this. The second gun, of which, is not upgradeable. And I've had JG's firing over 338fps, my JG G36c was shooting just over 400fps. So no, this isn't exactly correct. You cannot go off of the fps on the box. You'll need to get it chrono'd first. I'd also suggest playing with it a bit more before you dive into upgrading it. This is especially true if you haven't even fielded it yet.

I've never seen a box with an fps label of over 338. I don't know why, but I just haven't for that reason, I just kind of assumes it was illegal.

In Japan, they have strict FPS rules for guns. That's why TM's are lower FPS than most other top-end manufacturers (G&P, ect.) as they are restricted to a muzzle energy that doesn't exceed 1.00 joules. The U.S. doesn't have these rules though other countries mileage may vary.

Generally a good rule of thumb if you want a gun to last is to leave it alone until you absolutely have to start replacing gearbox internals.
Also as was already mentioned, get your gun chronoed. I'm pretty sure CYMA's shoot hot out of the box and chances are you are already close to 400 fps.

If you really can't live without upgrading the gun, have somebody do it for you. I struggled with a v2 gearbox first time I opened one. Now if you've never had gearbox experience, working on a v3 with that stupid trigger won't work out to well.
Most cyma ak's shoot around 370 and up from what I've seen, you shouldn't have a problem with the fps. Work on the hop up and barrel if you want to tinker with the gun.

Yep, I made the mistake of trying to "upgrade" my gearbox without experience. I thought it would be just a simple shim job, but the gearbox ended up being locked up for my first game at no limits. You have to be very careful about remembering exactly where each piece goes and in what position, otherwise you will screw something up. It doesn't help that I let it sit disassembled for weeks...

To be honest upgrading is not that hard. It's mostly a act of patience and precision, because you have to get everything done perfectly and correctly in order for it to function properly. With that said i would agree with everyone else and get a good tbb, hopup unit, and bucking before you screw around with the gearbox. Of i were you, I'd have someone else work on it if you have no experience and are not confident enough to do it yourself if you're that set on working on the internals.

You may even find members on here who would be willing to help you with it if you do decide to proceed with the upgrades.
