Promethus MS100 & MS110 fps on G36C?

[perky416]

Hi guys,

Does anybody have a Prometheus MS100 or MS110 spring fitted to their G36C? If so please could you tell me what FPS you get on either spring?

My AEG has a 10-20fps air drop however I threw away my original spring, with a Prometheus 6.03 barrel im getting around 320fps on the MS100 and 345fps on the MS110.

I think i know what is causing the air drop however i dont know what these springs are supposed to put out.

Regards

Times 3.28 by the number of the spring and that gives you the Fps. So M100 should be 328fps.
I would fix the air seal issue.
