AGM MP44 Spring and GearBox

[Skippy77]

I have replaced the spring from my AGM mp44 gearbox. The old spring was a lot shorter. The spring I out in was a 100 spring that I cut down just slightly longer than the old spring. However now the shots appear to be a lot slower.

 

Should I have put in the full sized spring?

Does anyone know know what type of gear box this is to replace/upgrade?

Yes, you should have put in the spring as it was.

An old worn out spring will be shorter as that is why it is worn out.

What sort of nozzle can I get as there are signs of wear and tear on it.

 

Do you also have to use grease or can you use any type of grease like lithium grease or Teflon type grease.
