Also, there's a spring chart somewhere on ASC that gives you max spring ratings on an upgraded gun.
Prometheus MS100 is about 345fps
MS90 ~300
MS110 ~380

Was with a TM P90... 300mm barrel.
Add 10 fps per 100mm... so a regular M4A1 will be around 360...
A lot of cheap brand of spring use funky ratings... and drop FPS or never have stablility... stick to Modify or Madbull. Both offer very stable readings across a whole bunch of springs.
Short gun = M110
Long gun = M100
370mm is the limit between..
