Corps de gerabox CNC pour réplique de la série CM.098 [CYMA]

Recently my stock gearbox from cyma.098 E edition cracked so i needed a new replacement and choose to go for an upgraded version which could "suffer/take more powerful spring" with that i mean it's more durable which it is by being CNC machined and tested for a 170spring.

While transplanting/installing some new parts from the cracked gearbox to the new CNC machined one was not a hurdle since it's a perfect fit with no deviation(atleast i didn't encounter any).

So after testing there was noticeable changes, the gun performed better than it was in semi-stock version when the stock gearbox was still intact. I still can't test for it's durability since it maybe 2 weeks since i got the parts but i hope it will take all the suffering from a m160sp spring.

The air tightness is great, shoots are very consistent and accurate, they sometimes start to deviate at around 85m+.

I'll also list the parts i changed in the gearbox aswell:
- Guarder SR25 cylinder
- Guarder m160sp spring
- 8mm bushings from cyma
- CNC aluminum double O ring nozzle 24.3mm
- Cnc Pom Double O-ring ball bearing piston head from FPS

Everything else inside the gearbox is stock and still in great shape.
