Spring vibration/echo

Hi guys,

 

Just swapped an m100 spring into my VFC SCAR that came with it as part of a sale. At the end of every cycle, there is a vibration/echoing noise coming from the mechbox.

I've read about it being that the spring is too short.

 

My question is:

how much damage can the spring do to my gearbox and Is it a big problem if I leave it in?

 

I'm just trying to find out if I am going to have to spend another tenner on a spring :P

 

Thanks in advance,

 

Andy

My CM.048 AK-74 has a Guarder SP100 spring downgrade and does that. So far it's been fine. I'm not planning to do anything about it, so we'll see if it turns out to be a problem.

Yeah, but I think the spring would have to be clipped to be that short. I think the sound may be a result of the spring vibrating from side to side. Some spring guides are quite thin; I know that the standard CYMA plastic ones are. This may allow more sideways movement than a fatter spring guide.
