Airsoft Canada - View Single Post - Extra piston movement after each shot on semi-auto in gearbox v.2

volteco · June 2nd, 2014, 15:05

Hey Guys,
I have the following low powered setup (340-360fps depending on hopup setting):
- v.2 gearbox
- Prometheus MS100SP spring
- Guarder cylinder, cylinder head and piston head
- Lonex spring guide with bearing
- 40D sorbo pad with neoprene pad

The issue I have is on every shot on semi-auto, after piston head hits the cylinder head, because of the sorbo pad (I guess) the piston moves back and forth again. When shooting, you can feel it like something rattles inside the gun after each shot. Here is a slow motion video of what happens:

If anyone had this issue and/or know how to get rid of it please let me know.
Thank you in advance!
