Upgrade set for sniper rifle CM.702 - 575 FPS [CYMA]

I installed this upgrade set into my CM.702 and I’ve been running it for a while now, so I already got a pretty good feel for how it performs in actual games. Right out of the box you can tell it’s built for higher power setups, everything feels tighter and more “sniper tuned” compared to stock internals.

After proper installation and a bit of fine tuning (and yes, it definitely benefits from proper lubrication), the whole bolt action became smoother and more consistent than I expected for a high-FPS kit. The compression feels strong and stable, and the shot consistency improved noticeably, especially when paired with heavier BBs.

It does require a bit more care than a drop-in beginner upgrade — you really need to pay attention to greasing and smooth cycling, otherwise it can feel a bit stiff. But once dialed in, it runs reliably and delivers solid performance in outdoor games.

Overall, it’s a strong upgrade set for anyone who wants to push their CM.702 into a more serious sniper setup, just not something you install without proper tuning and maintenance.

Very, very useful and high quality product!
I am definitely satisfied with it ever since I bought it, my CM702 has finally become worthwhile.
I can absolutely recommend it.
+1 tip: install it carefully into the gun, because it’s quite tricky at least it wasn’t easy for me.


Nagyon nagyon hasznos és jó minőségű termék! Határozottan meg vagyok vele elégedve, amióta megvettem végre ér is valamit a cm 702-esem. Mindenképpen csak ajánlani tudom. +1 javaslat óvatosan szereld a fegyverbe mert elég nehézkes, legalábbis nekem nem volt könnyű.

Very good product.
Cheap and good quality. It brings the performance around 570 FPS. It is not difficult to wind up the sniper rifle.
However, it should only be used with a steel cylinder!
The wall of the factory cylinder is damaged by the inner wall of the piston.

This upgrade is great, its easy to install. Its shoots just a bit harder en youre bb goed straighter.
I had to buy the cilinder to cause the original cilinder have out on me indont know it s from the upgrade or not but still great and cheap upgrade its worth it

easy to build into the cm.702a replica, power grown from 2,6J to 3,1J. but you will need heavy BB to achieve it because under 0.32g BBs it will produce around 2,8J top. the piston has rubber top, so made the shooting action quieter than the factory parts.
