Hello Everybody,

I own a Cyma 702A.
I have searched allot on which parts fits the replica.

Many people are speaking about a copie of the Sw m24 other say its the same as a MB01 Well.

I want to know for sure now.

For that i took my Cyma apart and took some pictues from the internals.

Piston length:

Cilinder length with out the part were the lever fits:

Innerbarrel length:

Personal i want to start with upgrading the Innerbarrel and Hopup unit.
But i dont know which hopup unit fits.

This one i though was right but then i read its only for Sw M24.

Thank you,

Does anyone know which mags from other m24 brands would fit the Cyma 702? I have the 702C but i think all are using the same. Can't seem to find any place where they sell them. Apologies for using this thread.

Im recently found this website with Cyma 702 parts.

Can someone vertify if they really fit?

Update:
I had contact with airsoftpro, they say the SW m24 hopup chamber doesnt fit!
Did someone try?

Check here the last two comments. http://www.airsoftsniperforum.com/44-others/14872-cyma-m24-cm-702-a.html
I also own this gun, and i'm searching everywhere to find what parts are good for it. I also stumbled into a french forum, and a friend translated for me, saying that the hop-up chamber from PDI Maruzen APS2 fits, and there they say that they havent seen a piston like this before(its like 2cm shorther than the VSR one...)

The PDI hopup works fine for mine. Not to expensive from Aliexpress

Good thing is, you can use any AEG type bucking with this hopup. Hard rubber or PDI W hold works really well. Bad thing is it will require a bit of filing to get the feeding and reload smoothened.

I'm looking for piston and trigger parts too!

I have also Cyma CM 702,
I just replaced inner barrel 6.01 mm purchased from here:
https://www.airsoftguns-europe.com/raven-inner-barrel-6-01mm-sw-m24-485mm-pdi
It has same length as original barrel (486 mm).
Next will be the steel cylinder:
http://airsoftpro.cz/en/gun-parts-u...vy-valec-pro-pusky-cyma-sws-m24-cm.702-detail
Only I am waiting confirmation of dimensions from airsoftpro.
Most of the piston, spring and spring guide sets (SW M24) are smaller in diameter, they are not good for cm.702.
I don't understand, why there are no main dimensions on webshop product pages, so we can be sure that part is good or not for us.
Anybody found piston for cm.702? Also hopup chamber?

On this post I found that VSR-10 has similar cylinder diameters as cyma 702:
http://www.airsoftsniperforum.com/32-general-sniper-talk/15382-piston-type-diameter.html
(outer 24 mm, inner ~22.45mm). I measured similar dimensions on my cm.702.
Anybody tried VSR-10 cylinder head, piston or spring set on cyma?

New info:
- I got the answer from airsoftpro.cz that they will have piston for cyma cm.702 in few weeks. (most of the M24 pistons and cylinders are smaller in diameter).
- Hopup chamber for cyma 702 will be produced only next year. Current can not fit into outer barrel.

Interesting info I found here.. I think this set would be good for cyma 702, but I didn't got any confirmation from PDI distributor so far.
X-FIRE PDI official distributor
quote:
"This cylinder is for SNOW WOLF M24 but that's 2 line. The one is using APS system,the other is VSR system.This cylinder set is for APS SYSTEM,If you're M24 is VSR system,you can't use this one.Please check it well."
CM.702 APS system has inner diameter of cylinder 22 mm.
VSR-10 piston can not be used on cyma, most important difference is the trigger lock part. On cyma its 90 deg, on VSR is under angle..

For me it's expensive for experimenting, but if I would be sure it's good, probably I would invest 15435 JPY. http://timein.org/exchangerate?c=JPY&n=15435
