Cyma Sr25 Quality

[Niels Henriksen DK]

Hi guys. I know it's a budget gun. I had bad experiences with the CA25. 

Does anyone have experiences with this gearbox and heavy springs? I would like to hit 2.5-2.8j (Danish fields allow quite a lot)

Will an m160-m170 spring tear up the gears and the box? 

I'll change motor. 

I wont be firing a lot.

As long as it has a good air seal so that the piston impact is cushioned by the air trapped between the piston and the bb and you check the shimming, I don't see how it's going to break.

Give the gearbox a nice radius (it's a free modification as long as you have a round file and has zero side effects, so it's worth doing).

I have a CYMA SR25 and the quality of it is surprisingly very good.  It is solid and works very well. The air sealing is also very good. I installed a Gate Titan, which in many other cases I do a full upgrade and change parts, but not with this.
