cyma ak 105 full metal; need help taking it apart putting back together
 

Hey there,
I just purchased this ask and I'd like to know how to properly strip it down and put it back together. If someone could bare with me I'd be most appreciative.

Thanks in advance

First of all, why do you need to do that first thing you do when you get it? I'd advise just playing with it out of the box (unless of course the spring is too strong and you're over limits). In which case I'd suggest paying someone like $30 to swap the spring for you.

Follow steps in reverse for assembly

Well like a lot people did use a video. This video should be similar to what you're getting CYMA CM035A DISASSEMBLY GUIDE WITH DELTA 1 PART 1 - YouTube

You can learn everything you need to know about airsoft on YouTube.

Since your new I'm going to offer you some good advice that will solve headaches and spent money down the road. Cyma Ak's ain't too bad for the bucks. With that said the internals ain't the greatest and will break down the road. Your best bet unless you have to swap out the spring (Cyma is know for being 420 ish and up in stock form sometimes) just leave it alone till something goes. At that time I would suggest you buy a better end complete gearbox. Unless you really want to learn and swap parts. This is time consuming and cost bucks. Some stuff parts wont work well with other aftermarket stuff, sometimes aftermarket stuff wont fit your model of AK either..most should. Honestly though, shoot it till it breaks and then rebuild as needed. Also as mentioned above, everything can be pretty much found on youtube. Lots of version 3 gearbox builds and break downs as already shown from replies.
