[steve grey]

Probably a simple one to many of you, but is there a set, spring strength to FPS output ?... as in, An M100 = FPS of about ??, where as an M90, would only give you around ?? ....thanks in advance.

Re: Spring to FPS values

The "M" is supposed to represent Meters per second with 0.2g. So M100 is 100 meters per second which is approx 328fps with 0.2g. However, how close you get to this is down to your setup and of course how close the actual spring is to it's rating. Most will be a little hotter than advertised, which is why you typically see M90's coming in at around 330fps, and M100's around 350fps.


For weight reference, the fully compressed weights by rating are approx;

M90 - 8kg
M100 - 8.5kg
M110 - 9kg
M120 - 10kg
